The Wireless Temperature Sensor with Data Backfill periodically measures Temperature (°C/°F) and wirelessly transmits the result to nearby Cloud Connectors (gateways) 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 (web application).
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.
Features
- High accuracy (±0.25°C after calibration)
- Can store up to 100,000 measurements
- Software verification level Class III with accuracy class 0.5
