AHT20 - Temperature and Humidity Sensor
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 2 Volt - 5 Volt. And with simple peripheral circuit, it performs stably even in harsh environments in the measuring range of -40 - +85 Celsius. 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.
