Sistem Monitoring dan Kendali Kipas Otomatis Berbasis IoT pada Kandang Ayam

Abstract

Temperature and humidity management in poultry houses is an important factor in maintaining suitable environmental conditions for poultry farming. This study was conducted at Hasan Farm, located in Kampung Cimuncang Cilik, Cimuncang Village, Serang District, Serang City, Banten Province. The operation of ventilation fans at the research site was still performed manually, resulting in suboptimal responses to temperature changes, while direct monitoring of the poultry house was inefficient in terms of time and labor. This study aims to design and implement an Internet of Things (IoT)-based automatic fan control system capable of monitoring and controlling poultry house conditions in real time. The system uses an ESP32 as the central controller, a DHT22 sensor to measure temperature and humidity, an HC-SR04 ultrasonic sensor to detect distance, a 4-channel relay module to control the actuators, a 16×2 I2C LCD for local display, and the Blynk application for monitoring, remote control, and notifications. Sensor data are processed by the ESP32 to automatically activate the fan when the temperature reaches or exceeds 30°C, while the lamp is controlled manually through Blynk. Test results show that the system can display temperature, humidity, and distance data in real time through the LCD and Blynk, control the relay, fan, and lamp according to the operating mode, and send notifications when the temperature exceeds the specified threshold. The system can effectively, efficiently, and responsively support integrated monitoring and control of poultry house conditions, thereby contributing to improved poultry farm productivity.
