The Wireless Temperature Sensor (Gen 2) 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 device can be configured to measure the temperature at regular intervals and report the measurements every 15 minutes. The number of temperature measurements taken in each 15-minute interval can be configured from 1 up to 30, for a measurement interval down to 30 seconds.
The Wireless Temperature Sensor (Gen 2) has touch functionality for simple installation and use.
