Self-powered Wireless BLE Beacon Module

SKU: TEL0173

DFRobot’s self-powered wireless BLE beacon module needs no battery. It uses a micro generator (converts press kinetic energy to electricity via electromagnetic induction) and a BLE RF circuit (rectifies/stores energy to broadcast signals). With a 100,000-press lifespan, it’s maintenance-free, ideal for wireless doorbells, call buttons, and state-monitoring applications.
