Bluetooth Sensor

Definition: A Bluetooth sensor is a compact device that integrates Bluetooth technology to wirelessly transmit and receive data. It enables seamless communication between the sensor and other Bluetooth-enabled devices, such as smartphones, tablets, computers, and smart hubs.


  • Sensor Element: This component measures a specific physical or environmental parameter, such as temperature, humidity, pressure, motion, light intensity, proximity, gas concentration, and more. It converts the physical stimulus into an electrical signal for processing and transmission.
  • Bluetooth Module: This module houses a Bluetooth transceiver and protocol stack, allowing the sensor to establish wireless connections and exchange data with other Bluetooth devices.


  1. Powering On: When activated, the Bluetooth sensor broadcasts its presence to nearby Bluetooth devices, awaiting connection requests.
  2. Establishing Connection: Once a compatible device initiates a connection, data transmission begins. The sensor transmits measured data to the connected device and can also receive commands or configuration settings in return.
