1. Product Overview

Aosong equipped the RH/T sensor module AM2301B with a newly designed ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensor, and a standard on-chip temperature sensor. Certainly, Aosong has greatly improved its performance, and it has even exceeded the reliability level of the previous generation of sensors. Aosong also improved the new generation of temperature and humidity sensors, to make its performance in harsh environments more stable. Meanwhile, Aosong has rigorously calibrated and tested every sensor. At the same time, the structural design of the product shape has a certain protective effect on the sensor, and Aosong equipped it with fixed mounting holes to make the product adapt to more installation scenarios.

2. Application Scenarios

The AM2301B is a kind of sensor of humidity and temperature with digital I²C output. Certainly, 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.
