1. Product Overview

The AHT25 temperature and humidity sensor are equipped with a newly designed ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensor element, and a standard temperature sensor element. Its performance has reached the industry’s advanced level. The improved new generation temperature and humidity sensor. AHT25 has a 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 easily replace in an application. Every sensor has been rigorously calibrated and tested. Due to the improvement and miniaturization of the sensor, its cost performance has become higher.

2. Application Scenarios

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.
