Sound and Light Control Relay Switch Module, Adjustable Delay 1-60s, Sensitivity & Voltage 5V-30V, Compatible with Various DIY Projects

Sound and Light Control Relay Switch Module, Adjustable Delay 1-60s, Sensitivity & Voltage 5V-30V, Compatible with Various DIY ProjectsFeatures:1. Dual Control Modes: Operate using voice/sound control only, or enable both sound and light control simultaneously for automated operation.2. Adjustable Sound Sensitivity: Features two-stage sound amplification with a sensitivity range from approximately 10 to 90 decibels, allowing precise threshold adjustment.3. Adjustable Light Sensitivity: Light intensity threshold is adjustable from about 10 to 10,000 Lux, covering a range from complete darkness to bright daylight.4. Customizable Delay Timer: Set a relay activation delay from 1 to 60 seconds. The delay time is capacitor-based and correlates with the triggering sound.5. Robust & Safe Design: Includes reverse polarity protection to prevent damage from incorrect power connection. Supports a wide input voltage range from 5V to 30V.Product Details:This intelligent control module automatically activates a connected device when it detects ambient sound exceeding your set threshold, keeping it powered for your preset delay period before turning off. The light control function can be enabled or disabled. When enabled, the device can be set to trigger only under certain light conditions (e.g., in darkness).The module comes with a microphone and a photosensitive resistor pre-soldered for demonstration. An extension cable is included to help minimize interference from relay switching sounds.Specifications:- Supply Voltage: 5V - 30V DC (Important: Remove the shorting cap if voltage is above 6V to avoid module damage.)- Sound Intensity Range: Adjustable, ~10 dB to 90 dB.- Light Intensity Threshold: Adjustable, ~10 Lux to 10,000 Lux.- Delay Time: Adjustable from 1 to 60 seconds.- Maximum Load: 10A / 220V AC.- Module Dimensions: 50mm (L) x 33mm (W) x 18mm (H). Includes M3 screw mounting holes.- Note: Module color (red or green) is shipped randomly.Setup & Calibration Guide:For optimal performance, calibration in your specific environment is recommended. Use the multi-turn potentiometers for fine adjustment.Basic Calibration Steps:1. Disable Light Control: Cover the photoresistor with the provided black tape (or disable the function).2. Connect Power: Ensure correct polarity (5V-30V). Remove the shorting cap if using a supply above 6V.3. Set Minimum Delay: Turn the delay adjustment knob fully counter-clockwise.4. Adjust Sound Sensitivity: In a quiet setting, turn the sound sensitivity knob clockwise until the relay just deactivates (LED turns off). Test by clapping or speaking, then fine-tune until it triggers reliably at your desired sound level.5. Set Delay Time: After setting sensitivity, slowly turn the delay knob clockwise until the relay stays on for your desired duration (up to 60 seconds) after a trigger sound.6. Enable Light Control (Optional): Remove the tape from the photoresistor. Adjust the light sensitivity knob—clockwise for activation in darker conditions, counter-clockwise for brighter conditions.Troubleshooting Tips:- Variable Delay Time: The delay is based on capacitor charge/discharge triggered by sound. A louder trigger sound results in a longer delay. Test consistently (e.g., using an air sensor blow) for reliable timing.- Relay Self-Triggering (Chatter): If the relay clicks repeatedly from its own sound, increase the distance between the microphone and relay using the extension cable. Alternatively, slightly reduce the sound sensitivity to filter out the relay's operating noise.
