This ultra-low power sensor node features the BlueNRG-2 Bluetooth Low Energy system-on-chip and a suite of ultra-low-power ST sensors, including a magnetometer, gyroscope, accelerometer, pressure, temperature and humidity, MEMS microphone and time-of-flight sensor. It is an ideal solution for applications ranging from smart home to smart agriculture, supply chain management, asset tracking and other industrial applications.
The BlueNRG-2 BLE SoC monitors environmental pressure, humidity and temperature sensor data, as well as motion data from the accelerator, gyroscope and magnetometer, which can be processed by firmware on the Cortex M0 core to provide functionality such as event detection and even object tracking in 3D space through powerful MEMS sensor fusion algorithms.
The Soc can also transmit obstacle distance information from the embedded time-of-flight sensor data.
The MEMS microphone allows audio and music transmission over Bluetooth low energy with appropriate firmware running on the core.
The ultra-low power features of each device and BLE connectivity allow a completely wireless node powered by a standard CR2032 coin battery, with the possibility of joining many nodes in extended BLE mesh networks.
The solution includes comprehensive firmware with ready-to-use examples, and a BLEsensor app for Android and iOS mobile devices completes the package with data visualization and node control functionality.
This very low power Bluetooth low energy (BLE) single-mode system-on-chip allows highly compact battery-powered node designs in compliance with Bluetooth 5.0 networking specifications, based on a Cortex M0 core able to support large network topology, such as mesh networks and real-time elaboration of sensor data.
The matching impedance of this ultra-miniature balun and harmonic filter is designed for the ST BlueNRG transceiver and manufactured for optimal RF performance.
