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.

Spoiled food detection, Arduino, MQ4 Methane gas sensor, LCD display, Wi-Fi ESP 8266, Alert message , LED.
