Fermion: AHT20 Temperature and Humidity Sensor (Breakout)
SKU DF-SEN0527
The AHT20 is a high-precision but low-cost temperature and humidity sensor, which is equipped with an improved MEMS semiconductor capacitive humidity sensor element. It features standard I2C interface and a wide voltage supply of 2V - 5V. And with the simple peripheral circuit, it performs stably even in harsh environments in the measuring range of -40~+85°C.
This sensor can be widely used for measuring the environmental temperature and humidity of home electronic equipment, the temperature and humidity of automobiles, and so on.
