UD Putra Jember located in East Java faces challenges in increasing productivity due to temperature instability in the incubator, which causes a high hatching failure rate. To overcome this, a temperature and humidity measuring device using a DHT-22 sensor and an ESP-32 microcontroller has been designed. The data obtained from the sensor is then analyzed by comparing it with a thermohygrometer to ensure measurement accuracy. The results show that the temperature measurement error ranges from 0°C to 0.2°C, while the humidity measurement error ranges from 0.8% to 1.3%. The relative error values range from 0% to 0.56% for temperature measurement and the relative error values range from 0% to 2.17% for humidity measurement, the error values are in accordance with the datasheet with a tolerance of 0.5°C for temperature measurement and 5% for humidity measurement and the relative error values do not exceed 10% which indicates good accuracy.
