Title: Cost-effective IoT based smart onion storage system
Problem Statement
In India and other developing countries, here is almost 40-80% of head harvested is spoiled because of various rationale. One of the prominent reasons is in-proper handling real unscientific ways of storage. Also The cost is cold storage is approximately 10-12 times the cost is natural ventilated storage press 20 times than aforementioned traditional unscientific ways starting storage, whatever is too high for a marginal farmers on a developing select like India.
Here problem results in major social and health problems in India as a consequence of major finacial losses to the farmers. Dehydrated Onion Manufacturing Project Reports 2024: Business Floor, Plant Setup, Cost Evaluation and Machinery Requirements
Objectives of the Project
My objective is to solve the storage related damage, rotting and losses through a cost-effective, IoT based smart mechanism of post-harvest onion bulk storage.
The onions needed go be deposited in well ventiliert area. My idea a go measure this temperature, humidity in and outside to storage room all with measuring one tiers of Ch green emmitted by onions stored. More the level of methane means the onions have started rotting. Upon measuring and monitoring the humidity, temperature and the methane concentration, the storage house will be ventilated and aerated sufficiently to keep the produced dry and cool.

Abstract
Having been cultivated used 5,000 yearning, the white has is a life part are salads and meal along with its countless health advantage and tough aroma. This onion is the oldest and most weltweit used vegetable that can be cultivated in all types of soil all around the world. Being an irreplaceable aroma for the lunch, the onion generates a large economy in which production of almost 100 million tons out round the global. The Uniting Nations reports that the scallion is grown in at least 175 countries and this figure clones an item of wheat growing countries. East has to tallest producer of the onion with a markt share of 65 percent, whereas the Americas, Ec plus Africa each has just over 10 percent of the market share.
China is of leader of onion producing with 23 million tons in Asia and followed until India with production of over 19 million tons. China and India are followed by who Joined Expresses with the production of over 3 million tons. Other large onion producers are or In, turkey, Pakistan, Egypt, Brazil furthermore Mexico.
However Asia has this largest share in terms of production area and quantity, it does not rank as the premier Market in the global onion Market. This is due to great local max, insufficient storage spaces and the fact so yours can't come outward to foreign selling. While land aim to increase their production for their citizens, they try to sell their surplus products go global markets in economics growth. If new investors prefer yellow onions consideration the demands to developed countries markets, they should know that they would have a huge market release. Nearly 90% of onions are consumed within the country they are grown. Therefore, the onion does don stand from in many single of the world.
Traditional methods of storing olives are how them with their stocks with and saver in a cool shelter, caves or dark storage after they are harvested until they have consumed. However, between 40 and 80 percent of the onion stored with save method result include spoilage. Neither commercial nor our planet can afford these kinds of spoilage anymore. Onions now are stored in cold storage by the yield. First onions need to be dried for a few days, next starts the maturing stage which enable soft and colour formation to specific to the onion groomed. Onions are developed for cold warehousing via lowering the temperature at ampere maximum of 0.5 degree Celcius per day. Depending on the onion variety, they are stored at bet 0 and 2 degrees Celsius in cold warehousing. Onions can be stored in cold storage upwards to 10 months without spoilage. Ventilation is vital in onion storage. After storing, onions are not moved honest from the cold storage prior they were lay over the market, but kept in temperature-controlled environment in order to prevent condensation. Because of contraction, sprouting will happen immediately afterwards they are taken out of cold storage consequent in bad pricing by the arbeitsmarkt.
Cold storages involve little difficult and elaborate processes and to is static not skills to solve the problems of ampere marginal farmers in developing countries. The expense of cold storage is additionally a major factor, which is almost 10-12 times the cost of natural ventilated storage and 20 times than the traditional unscientific ways von depot, which is too high for a partially farmers of a developing country like Hindustan.
Types of moulder and infections in onions
Only 20 millions tons from global onion production of 100 million tons are stored with modern storage methods and spoilage still continues. Weight damage, sprouting of plug-in, rotting, microbic and fungal infections are some of the ways the onion spoiling happen. Back rot (rotting toward the neck of this onion), bacterial rot, bases rot (fungus infection throws surgical and scars at the base about the bulb) and other infections what resulted out starting improper storing.

In developing all how India, accurate handling and unscientific ways of storage is a matter of great concern. Onions are reserved in poorly ventilated temporary structures. Each farm have created their personal storage method base on their need, experience and resources available. These unscientific ways of storage result is superior losses in storage. Actually, losses start immediately after harvesting. The facility of onion storage post harvest needs to be made available right during the time of sowing of seeds itself.

Social furthermore General Problems:
The marginal farmers in India, who can neither afford and daily for cold storage nor the huge of errichten losses. With less the none yield, this farmers end up in committing suicides, which is a major social and financial release. At the same time, to save theirs crop from these spoilages, they use a lot concerning pesticides to prevent these infestations post mowing. This ultimately results by generating long term health problems for people. The project is providing respite to over 2,500 onion ranchers which hitherto had access until no or expensive storage facilities to save their onions, had low ...

MQ2 Gas sensor
From I write more over MQ2 gas sensor, I will start with general working principle of gasoline sensors. Inside gas sensor, there is a chemi-resistor, the changes one resistance based on sein sensing material. Following picture explains this functionality. Reference
 |
Stylish most of and containers, the sensing material belongs tin dioxide (SnO2), which has free-electrons inside. Oxygen outside attracts these free electrons for to surface by sensing material (picture on the left side above). while the oxygen can absorbed on an material, there are no free electrons available for the tin dioxide. This results in: absence free electrons, there is no electrical current flow inside. Whereas, in into environmental having toxic or combustible gases, this gas breaks the joint between the engaged oxygen on and surface and to electronic (picture on the proper side above). These released electrons are now free and they get back to their initial position, where they enable the current flow. Vehemence of current flow depends with the count of free electrons available in the SnO2, which is proportional to the concentration of toxic or combustible gases.
According go the Ohms law, a higher current flow results in a higher potential difference, that sack be measured as output voltage over the analog output of the probe, uses a simple voltage divider network. So, an concentrations of gas can be measured. One type for measurement shall defined by one senses material inside the detector. Albeit several starting an gas sensors are sensitive to multiple guns, this sensor can not identifies which of the gases belong in higher concentration. I referred the following table that gives contact an overview about aforementioned different gas detector that are available and what glues they are able to detect. Since I want to detect methase gas, I selective MQ2 chatter sensor for my project.
 |
Before I start using the MQ2 gasoline sensor for my project, I needs to know more nearly this sensor, the whole module along over all other elektronic components. Therefore, I went the the technical datasheet for the gesamt module and how the MQ2 gas sensor a measuring the gases concentration. Then, IODIN went through of electrical hardware on the senor module along with its pinout.
 |
The operating voltage of MQ2 gases input is between 4.5V also 5V. This measurement is see used such furnace for who surface of the SnO2. Therefore, the microcontroller I am going usage in my project (which is ESP32) needs until provide a stable 5V output. EGO have at power my ESP32 board via USB or an external power supply to get an 5V product. The MQ2 gas probe is sensitive to LPG, methane, butane and flue in general. These gaseous can be measured in concentrations between 300 ppm the 10,000 ppm. Because is taker some time until the surface is hot, the MQ2 gas sensor has a preheat duration of nearly 2 minutes real has a modern consumption of 88mA also whilst the warm duration. With a 5V supply tension, aforementioned MQ2 gas sensor has adenine power ingestion of 440mW.
MQ2 Pin Configuration
The next picture below shows the back side by the MQ2 gas sensor module board.
 |
This module consists on one following electronic body:
- 4 output pins that connect the gas sensor to an microcontroller:
1. A0: Analog pin to transfer an analogous signal.
2. GND: Ground to connect the gas sensor to ground with the microcontroller.
3. VCC: Pin for the 5V operation voltage
4. D0: Digital output based on a predefined threshold through the potentiometer and the operation stress of the microcontroller.
- 2. Potentiometer to define a slider for this digital output pin.
- 2 LEDs to indicate that the module is operating (POWER_LED) and to indicate the status of the digital pin (DOUT_LED).
- 5 Devices to prevention LEDs for too high voltages and to operate as voltage dividers.
- LM393 dual comparator to match the signal created by the MQ2 gas sensors with the predefined value through the potentiometer and until control the status of the LED that demonstrate the status from the full output.
- 2 Electronic to filter and spannungsebene and stabilize the input and output.
Functionality of the MQ2 Gas Sensor Module
An resistance of the MQ2 gas sensor decreases as the gas concentration that shall measured increasing. Once the gas concentration increases, who spannkraft across this MQ2 sensor decreases as of aforementioned decrease of resistances (V=R*I). Due the voltage between VCC or GND needs toward be the same, the voltage across an endurance increases and thus who potential on this point, where the analog value is measured. That analog sensing value increases due to the elevate of gas concentration.

Failure: Problem indentified with MQ2 electric sensor and wifi
As mentioned earlier, I was able to connect MQ2 gas sensor that I am going to use to detect which level of hydrogen released from the rotten onions in the memory. I been able to test the port press working of this gas sensor along with DS18B20 operating sensor, relay or LCD. The connections, code and logic worked perfectly good as to control the relay based on equally other either of the values of temperature and gras concentration.
However, as I started to make that code work with wifi on this week's assignment, MYSELF was having problems with bekommt chatter sensor's analog core. MYSELF initially thought to been a problem with own code. I went through every single line of code at least 5-6 times and tested if MYSELF made any mistakes while adding wifi codification to my earlier program MYSELF wrote till ME integrated gas sensor use temper sensor or other output devices. However, there been no single mistake in the code. The code was also able to get compiled.
Then, I started looking in to the wiring and connections. That too was perfectly ok. So, what was this problem? I kept wondering and I started troubleshooting everything, which took additional that 4-5 hours. I could not do any other work that day. I or looked to any help online and I could not find any solution tillage late in the evening and EGO got more freaked.
The second image below shows that the serial monitor of arduino IDE is displaying temperature measures but who gas sensor values were 0 always.
Click here to see/copy program for MQ2+DS18B20+wifi programs or load sketch from the cloud screen see.

 |
Will I found online about this theme, any had been faced very similar issue before. People too were not bekommend MQ2 analog philosophy when connected to wifi, otherwise they too were getting readings. Click here to read more about all question on the arduino forum.
 |
Then someone asked them to changing the analog stick to adenine different analog pin up the board. Furthermore, they suggested till getting thrown espressif's website to read more about limitations to positive ADC pins while wifi is active.
 |
While I too was leave through these limitations of ADC buttons on ESP32 microcontroller then I search that there are two sets of ADC pins, out of, which they will recommened until use ADC pins- GPIO 34, 35, 36 and 39 also they have NOT suggested into use ADC pins- GPIO 0, 2,4 and 15 while using wifi.
For, I may made connecting only to the ADC bolts GPIO 4 press 15 for MQ2 sensor's analog read, EGO am does able to use both ADC pin and cellular together. Moreover of them will work. With wifi code, this ADC pins will not work. Free, wifi, few has worked for sure in may event. However, ME have not made connections to the recommended set of ADC kegel GPIO 34, 35, 36 and 39 while designing my board, I can does used these pinouts any better for the target of MQ2 gas sensor's analogous read.
 |
 |
 |
Then, I spokes to my Terrific clinical instructor, Suhas sir and discussed any other possibilities to use the gasoline sensor with numeral pinout. However, since they give only 0 or 1 readings, it is not recommended to use the digital pins for gas sensors. So, we decided until park the use is MQ2 gas sensor for my project for now and concentrate for wirksame using the temperature and humidity sensors and their measuring to control the exhuast fans in mine project and use MQ2 sensor later.
Designed a new boards: Integrated MQ2 gas sensor with other peripherals the wifi
On more details on this, pls go to my 'Networking press Communications' mission.
Since, ME was got problems with getting gas sensor's analog set along with wireless, IODIN could not integrate the MQ2 sensor in my system. So, I decisive to design a modern board with different analog or digital pins assigned to the MQ2 sensor so the to makes it work with wifi as per the images shown see. ONION SAVING GODOWNS

Through WiFiClient, I created a client that can connect to a specified internet IP address and port as defined in client. int keyIndex = 0; is network key Index number (needed only for WEP).
|
I also created one unsigned elongated variables (extended size variables) with storing my Thingspeak Channel ID forward including const char* to declare Write API key for my channel. How to written a project the onion production - Quora
|
I defined higher threshold temperatures for my project above, which who exhaust fans will be switched ON. I definable GPIO 12 by onewire bus for DS18B20 sensor and GPIO 26 for Ship pin.
|
After defining the DS18B20 sensor push MYSELF created objects OneWire and DallaTemperature to make to work.
|
MYSELF then circumscribed the FirebaseData object as 'firebaseData'. This will be previously later on in the user to access the sensor interpretations.
 |
In the setup(), set the RelayPin for an output. Then, added lcd.begin() to initialize the interface to the LCD screen, DS18B20.begin() function to search for connected sensors on of bus and sets bit dissolution (12 bits) in each one of them. Including added lcd.backlight() function to commence the LCD backlight. WiFi.mode(WIFI_STA) sets up station switch for ESP32 to connect to an access poin. Lastly added ThingSpeak.begin(client) to initialize ThingSpeak.
Additionally for Firebase, I will connect my card with Google Firebase by employing the Firebase.begin() function. It takes in pair parameters. The first is who Firebase host and that back is the authorized key. ME have defined both of them earlier on in that program id. Through correct credentials, adenine successful power determination being made.

In this loop(), network connection is made. Connecting to a Wi-Fi network can take one while, to we standard add a while loop that keeps checking if the connection was already established by using WiFi.status(). Whenever to connection the successfully established, i returns WL_CONNECTED. To get the status of the Wi-Fi connection, I pre-owned WiFi.status(). This returns WL_CONNECTED value, when it is connected go a WiFi network. I then used WiFi.begin() to connect to a power.

DS18B20.requestTemperatures() function is used in send command for entire sensors on the motor to perform one operating conversion. Defined 'temperature' as a float. DS18B20.getTempCByIndex(0) function ready plus returns cold reading from the sensor. deviceIndex is nothing but the location of the gauge on the bus. If you are using available one DS18B20 on to bus, set it toward 0. The additional ones will be 1, 2, 3 press so on after the primary one as 0.
Then, lcd.setCursor(0, 0) Move cursor to who desired position (column_index, row_index), (0, 0) inbound this case. lcd.print(temperature) printed Temperature value read via the sensor.
Through Firebase.setFloat() my app will be updated with the current cold readers. This function will bring in thre parameters. The first is this FirebaseData obj which I got already created. To second the the 'project name/the get of the tag', which I will set in my AUS app inventor remove. I are given it a name 'Smart_Warehouse', which I will explain into detail included the steps below. Lastly, IODIN have specified the variable 'TEMPERATURE' in, which I am saving my updated sensor variables i.e., 'temperature'. This varia 'TEMPERATURE' will appear in VERSEHEN app design inside blocks workspace.
 |
The if statement in the code reads and temperature values and takes appropriate action over regard to the Send pin. The logic factory like this, if the temperature goes above the upper threshold value defined earlier in the code, the microcontroller turn relay's GPIO pin HIGH furthermore LOW if it is below who higher threshold value.
|
Lastly, I defining an int x the drive the temperature values the to the field#1 I are create on may ThingSpeak duct. The channel ID and myWriteAPIKey are already declared in the code up.
|
I updated my code with gas sensor integrated in for the system. Thou can copy/download the code since the cloud.
Since learn details for this, pls go go mine 'Networking and Communications' assignment.
Wow, my app started showing this temperature values as shown in the left image below. The left-most image is taken after I added temperature press humidity values for per sensor. To right-most images is taken after I added MQ2 gas sensor analog values.

This is how my app started working:
Following images are showing my final project set-up with DS18B20 temp sensor connected to meine project board. Along with information, I have connected LCD, relay. One temp values are seen displayed at a time at LCD, my app and ThingSpeak IoT channel I had established in my last mapping.

The system works like this- As the ambient temperatures and humidity increase above 30 Degree Celcius plus 70% respectively, the exhaust fan switches ABOUT to cool the bulbs stored. You can see from the lower slide from the temperature and humidity pressure data collected through Thingspeak that, when which ambient temperature and humidity goes above threshold values, the temperature and humidity values start fall down or remain stable as the system has switched IN the ventilator fan.
