Features:
1. Ultimate Convenience: Achieves "one-time installation, permanent use" (during its physical lifespan) by completely removing the inconvenience of battery change.
2. Eco-Friendly & Energy-Efficient: Using no batteries lowers carbon emissions and heavy metal pollution.
3. Installation Freedom: The outside unit can be mounted anyplace (metal doors, glass, stone) without the need for wiring. The indoor unit is movable.
4. Stable and dependable: unaffected by battery deterioration, avoiding low-power failures.
System Architecture and Core Modules:
An interior receiver (bell) and an outdoor transmitter (button) make up the full system.
1. Outdoor Transmitter
Power Generation Module: o Technology selection: Electromagnetic induction generator (mainstream, mature) or piezoelectric ceramic generator (simpler structure, lesser power output).
Mechanism: Pressing the button drives a magnet through a coil or compresses piezoelectric material, resulting in immediate AC current.
Signal Processing and Transmission Module:
Main Control MCU: A low-power microcontroller activated when enough energy is present.
Mechanical and structural module.
Button Tactile Design: Must balance actuation force, travel distance, and power generation efficiency while delivering adequate tactile feedback.
Housing: High protection rating (IP65+), rainproof, dustproof, and temperature-resistant.
Mounting options include 3M sticky pads, screw mounting, and other techniques.
2. Indoor Receiver
Plug in the power module (USB/power adapter).
Wireless Receiver Module: Compatible with the transmitter protocol.
Alert and Interaction Module:
Audio alerts:
The built-in high-quality speaker supports polyphonic ringtones and has a multi-level volume adjustment.
Physical buttons include volume control, ringtone selection, and a pairing button.
Indicator lights indicate power, pairing, and operating condition.
Primary Use Cases:
Residential users (single-family homes, apartments, and renovated older communities).
Bed and breakfasts, modest studios, and retail stores.
Individuals that are highly accepting of technology and environmentally friendly solutions.
Households with elderly or youngsters who are concerned about forgetting to replace batteries.
