Fermion: BLE Sensor Beacon
Fermion: BLE Sensor Beacon, a wireless beacon that broadcasts sensor data via Bluetooth, with built-in 11-bit ADC acquisition and I2C write/read functionality, can be connected to digital or analogue sensors for data acquisition and broadcasting. Sensor data broadcasted by the beacon can be accessed within the beacon’s broadcast range using mobile phones, ESP32 and other devices that support BLE reception.
Fermion: BLE sensor beacons integrate low-power Bluetooth 5.3 technology with self-configurable data formats, such as iBeacon, Eddystone, user-defined, and more. The data format of the beacon broadcast, the content of the broadcast, the broadcast interval and so on can be configured through the graphical interface, without the need for any code programming to complete a Bluetooth beacon. After the configuration is completed, the device power supply is running as a Bluetooth beacon, which will automatically collect sensor data and broadcast to the outside world according to the configuration information. It is suitable for IoT sensor nodes, such as smart farms, offices, factories, warehouses and other scenarios in the data collection node.
