Gravity: AHT20 Temperature and Humidity Sensor
221 units will be
available shortly.
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°C ~ +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.
