## Description

Turn regular 3.3V sensors into wireless BLE sensor nodes with this 5 pack of Fermion BLE Sensor Beacons from DFRobot. Each beacon broadcasts data using Bluetooth Low Energy, so nearby BLE-capable devices such as smartphones and ESP32 boards can scan and receive the data without pairing.The Fermion version includes an 11-bit ADC, support for digital, analogue and I2C sensors, and multiple I/O pins that can be multiplexed to SDA/SCL. It is designed for IoT sensor deployments such as smart farms, offices, factories and warehouses, where running long sensor cables is inconvenient.Broadcast parameters can be configured using PC software, including formats such as iBeacon and Eddystone, broadcast interval, dynamic sensor power control and trigger broadcasts. Configuration requires a 3.3V USB-TTL tool, and the beacon can only be burned once, so test with “Run in RAM” before using “Burn/Program”. I2C configuration information cannot be tested through “Burn in RAM”; follow the product wiki carefully before burning.This pack includes Fermion BLE Beacon Sensor x5 and 8Pin connector x10.Features:BLE beacon operation: Broadcasts sensor data wirelessly using Bluetooth Low Energy without pairing.Unique identifier: Each beacon contains a unique identifier detectable by nearby Bluetooth devices.Sensor data broadcasting: Sensor data can be accessed within broadcast range using Bluetooth-equipped devices such as smartphones or ESP32.Built-in ADC: Includes a built-in 11-bit ADC.I2C interface: Supports real-time collection and broadcasting from I2C sensors in the Fermion version.Multi-sensor compatibility: Works with 3.3V digital/analog/I2C sensors.Low power consumption: Consumes only 650nA in sleep mode.Customisable broadcast parameters: Supports adjustable broadcasting format, interval, dynamic power control for sensors and trigger broadcasts.Broadcast format compatibility: Compatible with iBeacon, Eddystone and other official broadcasting formats.User-defined formats: Supports user-defined broadcasting formats.PC software configuration: Parameters can be configured through PC software.User friendly setup: Configuration does not require programming knowledge or Bluetooth protocol expertise.Graphical interface: Uses an intuitive graphical interface for setup.Automatic operation: Once configured, the device automatically collects sensor data and broadcasts it.Application: IoT Application.Application: Smart farms.Application: Smart offices.Application: Smart factories.Application: Smart warehouses.Compatible sensor: Fermion: SHT40 Temperature & Humidity Sensor (Breakout).Compatible sensor: Fermion: SGP40 Air Quality Sensor (Breakout).Compatible sensor: Fermion: MAX30102 PPG Heart Rate and Oximeter Sensor (Breakout, I2C/UART).Compatible sensor: Fermion: LIS2DW12 Triple Axis Accelerometer.Compatible sensor: Fermion: ICP-10111 Pressure Sensor (Breakout).Compatible sensor: Fermion: GR10-30 Gesture Sensor.Specifications:Operation Current: ＜10mAInput signal: Digital,Analog, I2COperation voltage: 1.1~3.6V DCInterface: 2*8P PinholeCR2032 Button Cell HolderMaximum number of simultaneously connected sensors: Digital/ Analog*1+I2C*1Operating Frequency: 2.4GHz ISMModulation: GFSKModulation: +5.0dBmPCB Size: 35mm*42mmADC Precision: 11bitNumbers of pins could used as SDA/SCL: 5Mounting Hole Size: Inner diameter of 2mm/outer diameter of 4mmA useful choice for distributed BLE sensor nodes, wireless garden monitoring, smart building sensing and other low-power IoT data collection projects.
