The DFRobot Gravity: BLE Sensor Beacon Pack (5x) is a set of low-power Bluetooth beacons, each a compact wireless device that broadcasts signals using BLE technology. These signals carry a unique identifier that can be detected by nearby devices equipped with Bluetooth technology, such as ESP32 and smartphones, that support BLE scanning. Notably, these beacons do not require pairing with devices to broadcast their data.
Each Gravity wireless BLE Sensor Beacon is equipped with a built-in 11-bit ADC, enabling it to gather data from both digital and analog sensors and broadcast it via Bluetooth. This allows users within the broadcasting range to access the sensor data on a Bluetooth-equipped device such as a smartphone or ESP32.
