Self-powered Wireless Switch (BLE Beacon)

The self-powered wireless switch series by DFRobot redefines the traditional wireless control landscape by eliminating the dependency on batteries. Utilizing an innovative micro power generator and energy storage RF circuit, the BLE Beacon model converts kinetic energy from each press into electrical power. This breakthrough means the switch is maintenance-free and perfectly suited for applications such as wireless doorbells, call buttons, ordering devices, and wall switches.

The technology eliminates battery-related issues like replacement, corrosion in humid environments, and environmental contamination from battery waste. This self-sustaining power mechanism guarantees uninterrupted operation while minimizing maintenance needs, offering a practical and eco-friendly solution.

Designed with enhanced wireless signal capabilities, the switch supports BLE 5.3, facilitating seamless integration with smartphones and other Bluetooth-enabled devices. This ensures hassle-free and flexible installations, enabling versatile control applications with robust wireless transmission, surpassing the previous 433MHz RF version's capabilities in both speed and resistance to interference.

Security is a priority, as each switch comes with a unique 6-byte address code ensuring reliable and interference-free transmission. This feature is crucial for maintaining consistent performance, even within complex wireless environments.

The durability of the switch is impressive, withstanding up to 100,000 presses. Compared to its predecessor, this model requires a lower press force and a shorter press distance, providing enhanced tactile feedback and user experience. Power efficiency is improved, with only 250 microjoules needed per press, as opposed to the previous requirement of 600 microjoules.

Particularly suitable for integration with ESP32 or other Bluetooth-enabled microcontrollers, the BLE beacon version offers greater flexibility by eliminating the need for a dedicated receiver. While the 433MHz version excels in scenarios requiring signal penetration through multiple walls, the BLE version boasts superior anti-interference and faster transmission rates, making it a more advanced choice for contemporary applications.

This upgraded self-powered wireless switch series is a leap forward in power efficiency, signal transmission, and user interface, providing an essential component for long-term, maintenance-free wireless control solutions across various applications.
