Iot Based Food Quality Monitoring System

Abstract

Food quality maintenance has become one of the major issues in the world. Recent surveys
show that approximately half of food commodities produced is going waste due to
inadequate maintenance of the environment where the food is stored. This calls for
technologies that monitors rotting and decaying of the food by the atmospheric factors like
temperature and humidity. Therefore, it is useful to deploy quality monitoring devices at food
stores. These quality monitoring devices keep a watch on the environmental factor that
cause or pace up decay of the food. Later, the environmental factors can be controlled like by
refrigeration, vacuum storage etc.
The proposed solution analyzes temperature, moisture, light as these parameters affect
nutritional values of food items such as fruits and vegetables, and makes the analysis results
accessible to the user via a mobile application. A web server is used for storage of data
values sensed in real time and also for analysis of results. User is alerted via messages,
heterogeneous sensors for various domains are employed for sensing the condition of food.
In this project, a similar food quality monitoring device will be designed that will keep watch
of environmental factors like temperature, humidity, and methane gas content. The device is
built on Arduino UNO. The Arduino board is interfaced with various sensors like DHT-11 to
monitor temperature and humidity, MQ4 to detect alcohol content. This is an IoT device
and sends the measured sensor data to an IoT platform. The ESP8266 Wi-Fi Module is
interfaced with the Arduino to connect it to the internet via Wi-Fi router. Using the IOT
platform environmental factors affecting the food storage can be monitored from anywhere,
anytime and from any device.
This project is created to tackle the issue of nourishment deterioration, with the assistance of
sensors which are utilized to identify the stale nourishment by detecting it constantly. The
discovery will be appeared through the sign dependent on freshness and nature of
nourishment by an alarm message sent to our enrolled cell phone.
