WMO states that temperature is an important parameter in life and defines temperature as a physical quantity that characterizes the average random motion of molecules in a physical body. The accuracy of temperature measurement on a thermometer is influenced by the selection of the right and accurate temperature sensor. There are various types of temperature sensors on the market with different principles sensor, such as electrical resistance, radiation, semiconductor, magnetic, etc. DHT11 and DHT22 sensors are the most commonly used sensors, easy to find on the market, and have the advantage of having two functions in one sensor, namely to measure air temperature and humidity. In addition, the DHT11, DHT22, DS18B20 sensors have the smallest deviation values among all existing temperature sensors. In this study, a comparison test of temperature accuracy was conducted using DHT11, DHT22, and DS18B20 sensors. Then an analysis is carried out to determine the work of the three sensors examined by laboratory calibration methods and field tests. In the Laboratory Calibration method, the DS18B20 performed the smallest uncertainty value at 0.17 ℃ followed by the DHT11 and DHT22 sensor at 0.18 ℃ of uncertainty value. It conformed with the correlation value at 0.999985, 0.999976, and 0.999098 for DS18B20, DHT22, and DHT11, respectively. Field testing is accomplished for 24 h of observation and compared with the Automatic Weather Station (AWS) data. The results of the two methods show that the three sensors have different correction values and uncertainty values with the DS18B20 sensor accuracy performance can reach 99.05%, followed by DHT22 and DHT11 at 98.15% and 97.19%, respectively.
