This research aims to design a monitoring system for temperature, humidity, and harmful gas levels in chicken coops using an internet of things (IoT) based system. The system design uses a DHT 22 sensor to detect temperature and humidity and an MQ-135 sensor to monitor the quality of ammonia gas (NH3). The designed system is also expected to control the fan and lights to maintain the cage's stable temperature and humidity. The data from the two sensors are connected to the internet network with the ESP8266 module and the Arduino Mega 2560 microcontroller. The data is then displayed on the LCD and sent to the smartphone application for remote notification via an 800L GSM SIM. Based on the test data carried out later, it can be concluded whether this IOT-based control system provides convenience for farmers to reduce mortality and delays in chicken growth. If successful, the data can be accessed in real-time using a smartphone application.
