Bluetooth BLE Sensor Beacon (Gravity: DFRobot)

AED 21.00



This Gravity wireless BLE Sensor Beacon with built-in 11-bit ADC is capable of collecting data from digital and analog sensors and broadcasting via Bluetooth. And users can access the sensor data within broadcasting range on a Bluetooth-equipped device like a smartphone, ESP32, etc.

Integrated with low-power BLE 5.3 technology, the BLE sensor beacon supports both LE and private-protocol broadcasting, and its data format works well with iBeacon, Eddystone, and other mainstream protocols. Besides, users can configure data format, broadcast content, and time intervals on a graphical interface as per their needs.

After configuration, it will run as a Bluetooth beacon when powered on, and collect and broadcast data automatically according to the settings. These sensor beacons can be used as IoT sensor nodes for data collection in many scenarios such as smart farms, offices, factories, and warehouses.

Note: Gravity: BLE sensor beacons need to be configured using the 3.3V USB-TTL tool.
