Development of an automatic temperature and humidity control system in a closed-house chicken coop to support smart farming

Abstract

Chicken farmers in Indonesia face significant challenges due to the tropical climate, which causes temperature and humidity fluctuations that can impact chicken health and productivity. This research aims to design and implement an automated temperature monitoring and control system for chicken coops to address these issues. The chicken coop comprises components such as a DHT11 sensor, an ATmega328, and a SIM900 module, which serves as a communication device when the coop's conditions deviate from comfort parameters. The coop is also equipped with a heater, fan, and blower. The system is designed to activate the heater when the temperature drops below a minimum threshold and activate the cooler when the temperature exceeds a maximum threshold. Calibration of the DHT11 sensor yielded an accuracy of 99.89%, indicating that this system has strong potential for application in innovative broiler chicken farming systems. The implementation of this system marks the first step in innovation for chicken coop environmental automation systems, specifically affordable, microcontroller-based coops with real-time data. This technology is expected to help farmers effectively monitor coop conditions and increase poultry productivity.
