This research aims to develop a temperature and humidity monitoring system using Arduino Uno and DHT22 sensor. Arduino Uno, as an open-source microcontroller, was chosen due to its ease of use and extensive community support. The DHT22 sensor is used to measure temperature and humidity with high accuracy, and has a wide measurement range. This system is designed to read temperature and humidity data periodically, display the results on the LCD, and calculate the heat index based on the data obtained. The research methods include system design, testing and calibration of the sensor, as well as analysis of the measurement data. The measurement results show that the temperature ranges from 29.40°C to 29.90°C, relative humidity between 75.50% to 80.40%, and the heat index between 311.96°C to 345.61°C. The analysis shows that the temperature and humidity increase non-linearly, with humidity slowing down over time. This study concludes that the integration of the DHT22 sensor with Arduino Uno can produce an effective and accurate environmental monitoring system, and provides recommendations for more consistent and accurate measurements in the future.
