In the modern era of technology and with increasing dependency on smart techniques like mobile phone, there is requirement of solving daily life tasks in a quick and easy ways. This project is based on food detection system using Arduino. The microcontroller panel has the capability to perform functions which include interpreting inputs and outputs and make the sensor to activate.
Generally food is stored in the refrigerator that lowers down the bacteria rate of production. Certain items which are perishable or not used for long term are to be detected and informed to the user.
This project is basically discussed to solve the food spoilage through sensors by continuously sensing the signals from the food and by displaying the ph value of methane on the 16*2 LCD panel along with buzzer and LED and also sends the alert message to the registered mobile phone.
The food we take can affect in any form of impurity that may happen due to storage or chemical changes within the food. In some countries, majority of people struggles on daily basis for food, due to preservation of foods and use of chemicals to artificially increase the time span of food causes people illness.
It is mandatory to grow a system that can assist people to identify the elegance of food or quality of food items. The quality of the food should checked to prevent it from spoiling under different environment conditions like temperature, humidity, vegetable/fruit characteristics , which will be helpful to check quality through different techniques.
The sensor senses the food quality through change in its colour. There are various signal processing and pattern recognition techniques to detect food intake time through sensors.
The rottedor not fit for usage food causes a major food related illness called as food poisoning, this is one of the diseases along with various other such diseases related to spoiled food. One of the main objectives of the food spoiler detector is that it will detect the gas released from the spoiled food and tell the user that the food is spoiled and take a look over food. Generally food is stored in the refrigerator that lowers down the bacteria rate of production. Certain items which are perishable or not usedfor long term are to be detected and informed to the user.

The technique for detection of spoiled food is much easier using two approaches. There are different approaches for the detection of the various gases that are released from food.
The proposed system is based on Arduino UNO which is a recognized prototyping board which is interfaced with gas sensors like MQ4 to distinguish smell.
The web switch which is a web modem connects the Arduino board to web net. The microcontroller board Arduino Uno along with food detection sensor MQ4 senses the gases coming out from the rotten food. The signal is transferred through a Wi-Fi device ESP 8266 AS.
The signals are sent to the user through a server. The buzzer, LED and LCD panel will also show the output from the sensor which is connected with the Arduino board.
VII. FUTURE SCOPE
The scope of the proposed system can be expanded by including more products like dairy, fruits etc. The system can incorporate different other sensors like pressure, temperature, moisture etc. Different other techniques like nano technology, artificial neutral network can be also be used for further improvement in result. These techniques can use this data for better result in future about food spoilage.
We are grateful to our guide Prof. M. RAVI KUMAR for this continuous support and guidance. Through his guidance, we were able to successfully complete our project. Our sincere thanks go to Dr. P. SATISH KUMAR, Head of the Department of Electronics and Communication Engineering at ACE Engineering College, for his support and time.
The early detection of the gases from different food items like ammonia, methane etc. can help the gas sensor to detect gas emission from food items even before the presence of any visible sign of spoilage. The consumer gets the information about the food item wherein he can monitor the perish ability of that food item. This will help in maintenance of health and prevents the consumer from consuming bad food. The use of technology helps in food processing industry wherein they can mention the duration of perish ability of the food item on the packet so that proper control on consumption can be done. The monitoring and detection of the food items is very necessary as most of the consumers buy packed food from the malls wherein date of expiry is important parameter.
