5pcs ASAIR AHT21B Digital Temperature Humidity Sensor Modules with Compact Size (without Dust Cover)

5pcs ASAIR AHT21B Digital Temperature Humidity Sensor Modules with Compact Size (without Dust Cover)

Description:
AHT21B is a newly upgraded product. It is equipped with a dedicated ASIC sensor chip, a high-performance semiconductor silicon-based capacitive humidity sensor, and a standard on-chip temperature sensor. It also uses the standard I²C data output signal format.

Its performance has been greatly improved and exceeds the reliability level of the previous generation of sensors. After improvement, its performance is more stable in high temperature and high humidity environment. At the same time, the accuracy, response time and measurement range of AHT21B have been greatly improved.

Every sensor is rigorously calibrated and tested before delivery to ensure that it meets the needs of large-scale applications.
