BLE-Mesh Communication

This device is designed to be part of a mesh communication network using Bluetooth Low Energy (BLE) technology. Its main function is to act as a node within that network.

The device can send and receive data over the BLE mesh network, enabling efficient communication between multiple nodes distributed across a given area. Its components include a low-power microcontroller optimised for BLE applications, a PIR sensor, a noise sensor, accelerometer and gyroscope for motion and vibration detection, a temperature and humidity sensor, an ambient light sensor and a lithium battery charger. All of this is packed into a compact design inside a plastic case worn on the wrist.

Together with other identical devices configured as anchors, it can receive iBeacons and locate nodes in space through anchor triangulation, making it possible to track people or objects indoors without GPS.
