E FRESH- DETECTION OF FOOD FRESHNESS

Computer Engineering

Food safety and hygiene is a vital concern so as to prevent the food wastage. The Quality of the foodstuff needed to be surveilled and it must be prevented from perished by the atmospheric factors like temperature, humidity etc. Hence, it is useful to establish a quality monitoring devices at food stores. These quality monitoring devices keep a watch on the environmental factor that speed up decay of the foodstuff. Later on, the environmental factors can be subdued like by refrigeration, vacuum storage etc. The device is built on using an Arduino UNO, a prototyping board. The Arduino board is interfaced with sensors like a MQ-3 sensor to detect gas odour content, a moisture sensor and a pH sensor. This is an IoT device which will send the measured sensor datas to an IoT platform. The ESP8266 Wi-Fi Modem is interfaced with the Arduino which is then connected to the internet via a Wi-Fi router. The sensor data is also displayed on a LCD display which is then interfaced with the Arduino UNO. The IoT platform is used for logging and monitoring all the sensor data to an embedded spot.
