Abstract
The presented research relates to an IoT based device for sensing quality of food items using sensors, and more particularly relates to a device which shows its results through a mobile application, and further the user can check the quality of food item on his/her mobile device and proposes the work done in shooting up the efficiency of a device that detects the presence of different parameters in a food item on which it is judged to be fresh or tainted, at an early stage with the help of sensors, basically alerting us that if the food item is fine to consume or not. Due to the increasing number of food-borne diseases globally, the detection of food consumption has become an essential aspect of modern life. The system includes, but not limited to, a plurality of sensors for sensing varied parameters of a food item; a microcontroller unit for processing the signal received from the sensors; a mobile interface to show the results for freshness and quality about the food items. Different sensors detect the freshness of different food items based on various parameters like moisture, ethanol and alcohol content and humidity in the environment. Eat Fresh device mainly consist of a node microcontroller unit (MCU) and different types of sensors like ethanol sensor, humidity sensor, moisture sensor. The analogue results are passed to the pins of the Node microcontroller unit (MCU) which already have an inbuilt ADC (analogue to digital converter) that converts the analogue value to digital value. This device ‘Eat-Fresh’ is capable enough to help us check the safety of the food. Hence, preventing deaths due to food poisoning and helping us to put a stop on the wastage of food.
