The Wireless Temperature Sensor (2nd Gen) measures the surrounding temperature and wirelessly transmits the result to a Cloud Connector (Gateway) via SecureDataShot™ wireless protocol. The Cloud Connector relays temperature readings to a Cloud Service where the data is made available through a web app called Studio or through the developer APIs for easy integration into other systems.
The Wireless Temperature 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 Temperature Sensor (2nd Gen) 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.
