AHT21B temperature and humidity sensor wide voltage I2C communication high-precision digital module original genuine product
AHT21B temperature and humidity sensor
Product Descriptions
AHT21B is equipped with a newly designed ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensor component and
a standard on-chip temperature sensor component. Its performance has been greatly improved and even beyond the reliability level of the
previous generation of sensor, which make it more stable in the harsh conditions. Each sensor had been rigorously calibrated and tested. Due to
the improvement and miniaturization of the sensors, it is more cost-effective.
Product Applications
The AHT21B is a kind of sensor of humidity and temperature with digital I²C output. It can be applied to HVAC, dehumidifier, testing and
inspection equipment, consumer products, automobiles, automatic control, data loggers, weather stations, home appliances, humidity control,
medical and other application fields which need to detect and control temperature and humidity.
