Description
Wireless remote controls are common in daily life, but they often rely on batteries, which can be inconvenient to replace and may contribute to environmental pollution. Did you know that it is possible to use wireless remote controls without batteries?
DFRobot's self-powered wireless switch uses a micro-generator and a 433Mhz radio frequency circuit to transmit signals wirelessly, without the need for batteries. The micro-generator converts the kinetic energy of pressing the switch into electricity, which is then stored by the RF circuit and used to send a wireless signal. This switch is suitable for long-term monitoring of pressing, collision, or other state changes, and can be used in applications such as wireless doorbells, pagers, food ordering devices, and wall switches.
To use this product, you will need a receiver, such as DFRobot's Gravity: Digital Wireless Switch Receiver (433MHz) or any other receiver that supports EV1527 decoding format and 10Kbps decoding rate.
