Accurate air management. Precision engineered in Germany, aërQ Temperature & Humidity Sensor is small in size but big on impact. 1 tiny sensor. 4 major measurements integral to any Z-Wave system automating heating, cooling or air health.

aërQ Temperature & Humidity Sensor is small. Really small. At 35mm (1.38") wide, it's only a little wider than a coin cell battery. It's been crafted that size so that it can be installed almost anywhere you need to measure temperature and humidity, and analyse some attributes of air health. Precision engineered, its accuracy and focus allow it to enhance the measurements your automation systems receive from other sensors while its size allows for multiple sensors to be unobtrusively installed in large-space rooms.

A single coin-cell battery keeps measuring for years. Accurately.

 German-engineered around a single, inexpensive, CR2477, coin-cell battery, aërQ Temperature & Humidity Sensor’s use of ultra-low power Gen7 and S2 Z-Wave technologies allows it to work for up to 2 years before you need to change its battery. And changing its batterry is a breeze: simply separate the two parts, recycle the existing battery, and slide in a new one. aërQ Temperature & Humidity Sensor will be up and measuring again in moments.
