Temperature Sensor


The Wireless Temperature Sensor periodically measures Temperature (°C/°F) 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 5 min, 15 min, 30 min, 45 min, or 60 min. 

There are two versions of this sensor available: one with Data Backfill and one without Data Backfill, each optionally equipped with a Calibration feature. Both versions come in two variants, EU and US, designed to meet specific regional certifications, compliance standards, and wireless communication needs. For more information, see the datasheet.
