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 Wireless Humidity Sensor uses Heartbeat Interval (HBI) to transmit a message notifying the system that it is present and operational, which can be set to 15 min, 30 min, 45 min, or 60 min.
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 and one for the US, due to different certifications, compliances, and wireless communication.
