Temperature Sensor (2nd Gen)


The Wireless Temperature Sensor (2nd Gen) measures the surrounding temperature and wirelessly transmits the result to nearby Cloud Connectors (gateways) at a predetermined Heartbeat Interval (HBI) via the SecureDataShot™ protocol. Cloud Connectors relay sensor data to the cloud via cellular or ethernet connectivity. From the cloud, the data can be integrated into other services using REST APIs and webhooks or viewed directly in DT Studio.

The Wireless Temperature Sensor uses 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.  

This sensor comes in two versions: EU (Product ID: 102150) and US (Product ID: 102152), each tailored to meet distinct regional certifications, compliances, and wireless communication requirements.
