Generic 220AC Acoustic-Light Sensor Switch Module - Auto On/Off Light Control
This 220V AC Acoustic-Light Sensor Module provides automatic on/off control for lighting loads up to 60W. It integrates a sound-activated switch with a built-in LDR (Light Dependent Resistor) to enable operation only in dark environments, making it ideal for corridor, staircase, and warehouse lighting automation.
Features
- Dual-mode operation: Sound-activated switching only in dark conditions via onboard LDR.
- Direct 180-240V AC operation, eliminating the need for a separate DC power supply.
- Supports a load power of ≤60W for LED/incandescent or ≤35W for energy-saving/fluorescent lamps.
- Sound sensing range of 4-10 meters for reliable trigger detection.
- Integrated timer keeps the connected light illuminated for approximately one minute after activation.

The 220AC Acoustic-Light Sensor Module is a self-contained control unit designed for mains-powered lighting automation. It operates on the principle of acoustic detection, where a built-in microphone senses sound events (e.g., claps, footsteps). This acoustic trigger is gated by a photoresistive light sensor (LDR), which ensures the module remains dormant during daylight or other illuminated conditions, activating the switch only when ambient light levels are low.
Engineered for direct integration into 220V AC lighting circuits, the module features robust internal relay switching and transient protection suitable for residential and light commercial environments. Its operation is straightforward: when darkness is detected and a qualifying sound is sensed, the internal relay closes, powering the connected load for a fixed duration before automatically resetting. This design offers a simple, energy-efficient solution for hands-free lighting control.
