Product description: Self-powered wireless switch - BLE Beacon - wireless switch - DFRobot TEL0173
Self-powered BLE Beacon wireless switch manufactured by DFRobot . It is equipped with a micro power generator and RF energy storage circuit that captures the kinetic energy from each press and converts it into electrical energy . Thanks to this, the switch does not need a battery or maintenance. The captured energy from each press is stored and used to transmit wireless signals. The switch is easy to install, supports BLE 5.3 , offering interference-free wireless signal transmission, thanks to GFSK modulation. The wireless switch is compatible with ESP32 , allows integration with smartphones and other Bluetooth- enabled devices. BLE Beacon provides faster transmission speeds (1 Mbps) compared to the Self-powered Wireless Switch (433 MHz RF) version. The switch performance is rated for 100,000 presses , the minimum pressing force is only 1,300 g, and the energy efficiency is 250 µJ .
The manufacturer provides a detailed user guide . You will find there, among other things, a connection diagram and sample program codes - check it out!
