AHT25 Integrated Temperature and Humidity Sensor


Key Benefits:

•Fully calibrated

•Digital output, I²C interface

•Excellent long-term stability

•Quick response and strong anti-interference ability


General Information:

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.



The AHT25 can be widely used in consumer electronics, medical, automotive, industrial, meteorological and other fields, such as: HVAC, dehumidifiers and refrigerators and other home appliances, testing and testing equipment and other related temperature and humidity testing and control products.
