Prediction system of chicken meat expiration time based on polynomial regression using NodeMCU ESP8266 and MQ137 sensor

Food waste is a severe problem in Indonesia. Based on data from the Barilla Center for and Nutrition, Indonesia ranks second food per person each year. The FAO also shows that there are 13 million metric tons of wasted, equal to consumption 11% Indonesia’s population (around 28 people) One factor consumer’s misinformation expired date. Not all items have “Best-Before Date,” especially meat sold traditional markets some supermarkets. Even if it exists, could be less accurate because only follows Standard Operational Procedure supermarket, which must within three days. Therefore, our research aims design device can detect expiration time using IoT (Internet Things). This will developed gas sensor MQ137 detecting level NH3 released by meat. Detection results sent via internet Firebase. processed polynomial regression produce prediction chicken meat’s time. Lastly, easily accessed through an Android application. In this paper, we present initial works develop predicting paper presents performance evaluation device.
