Product Summary

The AHT25 temperature and humidity sensor is equipped with a newly designed ASIC

dedicated chip, an improved MEMS semiconductor capacitive humidity sensor element and

a standard temperature sensor element, and its performance has reached the industry's

advanced level. The improved new generation temperature and humidity sensor AHT25 has

more stable performance in harsh environments and can maintain good accuracy in a larger

measurement range. AHT25 uses standard-pitch plug-in connectors, which can be easily

replaced in application. Every sensor has been rigorously calibrated and tested. Due to the

improvement and miniaturization of the sensor, its cost performance has become higher.
