The DHT20 is an upgraded humidity and temperature sensor featuring a dedicated ASIC sensor chip, a capacitive humidity sensor, and an integrated temperature sensor. It provides digital output via the IC protocol, offering superior performance and stability, especially in high-temperature and high-humidity environments. The DHT20 boasts improved accuracy, faster response times, and a wider measurement range compared to its predecessor, the DHT11. Each unit is rigorously calibrated and tested for large-scale applications.
