Self-powered Wireless Switch (433Mhz)

The self-powered wireless switch from DFRobot revolutionizes remote control technology by eliminating the need for conventional batteries. Utilizing a micro-generator and a 433Mhz radio frequency circuit, the switch capitalizes on electromagnetic induction. When the switch is pressed, kinetic energy is transformed into electrical energy, which is then rectified and stored by the RF circuit to transmit a wireless signal.

This technology not only reduces waste and potential environmental harm caused by battery disposal but also simplifies device maintenance by eliminating the need for battery replacement. Suitable for applications where long-term, maintenance-free operation is desired, this switch is ideal for wireless doorbells, pagers, food ordering devices, and wall switches, among others.

A compatible receiver, such as the Gravity: Digital Wireless Switch Receiver (433MHz) or any receiver supporting the EV1527 decoding format and 10Kbps decoding rate, is necessary for operation. This innovative solution offers a reliable and environmentally friendly option for various applications, adding convenience and sustainability to everyday devices.
