Design And Development Of A Server Room Temperature Monitoring System Using ESP32 And A DHT11 Sensor At PT. Samdo Karya Utama Textile

Abstract

The server room is a critical facility that supports information technology operations, so the room temperature must be monitored to maintain device performance. Based on observations at PT Samdo Karya Utama Textile, temperature monitoring is still performed manually, which could potentially cause delays in detecting temperature increases. This study aims to design a server room temperature monitoring system using an ESP32 microcontroller, a DHT11 sensor, a 16×2 I2C LCD, and a buzzer as an early warning system. The research methods include observation, hardware and software design, implementation, and functional testing. The results show that the system is capable of reading temperatures in real time, displaying measurement results on the LCD, and automatically activating the buzzer when the temperature exceeds 30°C. Thus, the designed system can help improve the effectiveness of server room temperature monitoring and provide early warnings to reduce the risk of equipment damage due to overheating.
