General Information:

The RH/T sensor module AM2301B is equipped with a newly designed ASIC dedicated chip, an improved MEMS semicond uctor capacitive humidity sensor and a standard on-chip temperature sensor, its performance has been greatly improved or even exceeded the reliability level of the previous generation of sensors, the new generation of temperature and humidity se nsor, improved to make its performance in harsh environments more stable. Every sensor has been rigorously calibrated an d tested. The structural design of the product shape has a certain protective effect on the sensor, and it is equipped with fixe d mounting holes to make the product adapt to more installation scenarios.


The AM2301B 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.
