The Wireless Humidity Sensor measures the surrounding humidity and temperature, and wirelessly transmits the result to a Cloud Connector (Gateway) via SecureDataShot™ technology. The Cloud Connector will relay the temperature and relative humidity readings to the DT Cloud.

The readings are performed at 15-minute intervals.

The Wireless Humidity Sensor has touch functionality for simple installation and use.

EU and US variants

This sensor is available in two variants, one for the EU (101851) and one for the US (101895) due to different requirements on certifications, compliances, and wireless communication.
