Fermion: AHT20 Temperature and Humidity Sensor (Breakout)

The AHT20 is an outstanding temperature and humidity sensor. It offers high precision at a low cost, thanks to its advanced MEMS semiconductor capacitive humidity sensor element. With a standard I2C interface and a wide voltage supply ranging from 2V to 5V, it's incredibly versatile. Its simple peripheral circuit ensures stable performance even in harsh conditions, measuring temperatures from -40°C to +85°C. This sensor has a wide range of applications. You can use it to measure environmental temperature and humidity in home electronics and automobiles. It features digital output via an I2C interface, excellent long - term stability, quick response, and strong anti - interference ability. Applications include HVAC, dehumidifiers, testing equipment, consumer appliances, automobiles, automatic control, data loggers, and weather stations. Specification details: The module operates on a DC voltage of 2V - 5V, has an I2C output signal with an address of 0×38, and measures 30mm×20.5mm (1.18×0.81 inches). The AHT20 chip has a relative humidity resolution of 0.024 %RH with an accuracy error of ±2% RH, and for temperature, a resolution of 0.01°C with an accuracy error of ±0.3°C. Documents available are product wiki, 2D dimensions, 2D dimensions in CAD, 3D STP, and circuit diagram SCH. The shipping list includes one Fermion: AHT20 Temperature and Humidity Sensor and one 2.54 - 4P Black Single - row Pin Header.

Using the Fermion AHT20 temperature and humidity sensor is easy. First, connect it to your device following the provided connection diagram. Make sure to connect it within the 2V - 5V voltage range. Once connected, the sensor will start measuring temperature and humidity in real - time. When using it, avoid exposing it to extreme conditions outside the -40°C to +85°C temperature range and 0 - 100% RH humidity range. For maintenance, keep the sensor clean and dry. If you notice any abnormal readings, check the connections and make sure the voltage supply is stable. Refer to the product wiki and circuit diagram for more detailed troubleshooting. With proper use and care, this sensor will provide accurate measurements for a long time.
