Design and Implementation of Temperature and Humidity Monitoring and Control System in IoTbased Chicken Eggs Incubator

Temperature and humidity during the hatching of chicken eggs greatly determine its success. Inconsistent egg turning causes slow embryo development. The number of eggs can affect temperature and humidity if not managed properly. This research aims to build an IoT-based control and monitoring system for hatching chicken eggs using ESP32 WROOM, DHT22, ESP32-CAM and PIR sensors. This research uses an experimental method. The research benefit is monitoring temperature and humidity values in the incubator and controlling the eggs’ turning. ESP32 WROOM 32 is used as a data processing unit. DHT22 is used as a temperature and humidity sensor. ESP32-CAM is used to monitor the condition of the eggs in the incubator. The PIR sensor is used to detect hatching eggs. In addition, a stepper motor is used to rotate the roller rack so that the eggs can be turned over. The research results show that the temperature in the incubator can be stabilized at $37^{\circ} \mathrm{C}-39^{\circ} \mathrm{C}$. Egg turning can be done automatically and regularly every day. The Blynk application can display the temperature and humidity in the incubator and stream the incubator conditions. It is hoped that the results of this research will increase the ease of managing the hatching of chicken eggs.
