Abstract

Most available commercial incubators are considered not appropriate for certain food processing such as for crackers drying and also considerably expensive. Besides, they do not have distance monitoring and control features. The objective of this article is to present the development process of an incubator prototype which has distance monitoring and control feature built based on the components commercially available in the market involving  traditional stove-based oven, electric heater, DHT22 temperature sensor, ESP8266 microcontroller, buzzer, and LCD OLED display. The incubator was equipped with the Blynk platform of a smartphone for distance control and monitoring. The functional test results showed that the developed incubator works well as expected. The calibration testing results suggested that temperature measurement by using the developed system has inaccuracy of 0.34% when compared to measurement by using a commercial thermometer. To validate its function in actual condition, the incubator was used for drying rice crackers. The rice crackers were dried at the temperature of 70  with a duration of 5 hours. It can be observed that the drying result by using the developed incubator was comparable to that of drying by direct sunlight on a sunny day with a duration of 16 hours.

Abstract

Conventional incubators for heating food generally can be operated manually by both its temperature level and heating duration. This condition provides risk that the food will be heated inappropriately both at its temperature level and heating duration which in turn can decrease food quality. The objective of this article is to develop an incubator for heating food which is equipped with a food object detection based automatic heating process and using internet of things (IoT) technology for distance monitoring and control, which detects the type of food and heating it automatically at both temperature level and duration. The incubator was developed using components available in the market including GY-906-DCI sensor, OV5647 camera, Raspberry Pi 4, NodeMCU microcontroller, and Telegram bot. Testing results showed that the developed incubator system was able to detect food types in real-time, as well as automatically set temperature and incubation time parameters based on it. It was able to maintain a stable incubation temperature, with an average error of 2.74% and a temperature deviation of 1.23 °C. The developed incubator potentially improves safety and user convenience where the food is heated properly both at its temperature level and heating duration.
