Fermion: AHT20 Temperature and Humidity Sensor (Breakout)

We have ✅ 8 available of the DF-SEN0527 in our Sydney warehouse. An extra 76 units will be available shortly.

Express post delivery (2-5 business days)

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.
