The Aeotec aerQ Temperature & Humidity Sensor is a 4-in-1 environmental sensor that features aerQ technology used to monitor indoor temperature humidity dew formation and air quality within a single room and sends data to your Z-Wave automation hub. The sensor is compatible with all major Z-Wave hubs and controllers. Monitor Indoor Environments in Four Different Ways: Temperature - aerQ technology monitors and reports temperatures between -10C and 65C (14F and 149F) and with an accuracy of +/-1.8F/+/-1C. Humidity - AerQ technology can measure a space s relative humidity at ranges between 0% and 80% and with an accuracy of +/-3%. Dew Formation - aerQ technology measures the relative dew point of it s installed location separate from measured relative humidity. Air Quality - AerQ technology calculates the potential for spores forming based on measured poor quality air. The sensor comes with a double-sided tape to mount onto virtually any flat surface. If your Z-Wave controller/hub features SmartStart compatibility you can scan the QR code on the sensor through your Z-Wave hub s mobile app and the sensor will be automatically included into your Z-Wave network.
