Fermion: AHT20 Temperature and Humidity Sensor Breakout

The AHT20 is a temperature and humidity sensor that is both accurate and affordable. It has a high-quality MEMS semiconductor capacitive humidity sensor element and a standard I2C interface, which allows it to be used with a wide range of voltage supplies (between 2V and 5V). This sensor is able to function consistently in harsh environments and has a temperature measurement range of -40C to 85C. It can be utilized for various applications such as monitoring the temperature and humidity in home electronics and automobiles.
