Sensors are battery-powered devices that measure a physical property - for example temperature. Sensors are linked to a tracker that will periodically records the sensor measurement values using Bluetooth Low Energy (BLE) communication signals.

Refer to each tracker's technical specifications to know whether it supports BLE sensors.
