Voice Control Delay Switch Module Sound Activated DC 3–9V

Voice Control Delay Switch Module – Sound Activated DC 3–9V

Upgrade your lighting setup with this compact Voice Control Delay Switch Module. Designed to respond to sound, this intelligent SMD module automatically turns lights on when it detects a noise and switches them off after a preset delay — perfect for hallways, stairwells, closets, garages, and any space where hands-free lighting is a convenience win.

Key Features

• Sound-Activated Switching: Built-in microphone sensor detects ambient sound and triggers the relay output instantly.
• Auto On/Off Delay: Light stays on for a set delay period after the sound event, then switches off automatically to save energy.
• Wide Voltage Range: Operates on DC 3V–9V, making it compatible with a broad range of low-voltage lighting and DIY electronics projects.
• Compact SMD Design: Surface-mount design keeps the module small and easy to integrate into your circuit board or project enclosure.
• Customizable Quantities: Available in packs of 1, 5, or 10 pieces — ideal for single prototypes or bulk DIY builds.
• Easy Integration: Minimal external components required; straightforward wiring makes installation accessible for hobbyists and engineers alike.

Frequently Asked Questions

Q: How does the Voice Control Delay Switch Module work?

A: The module uses a built-in microphone sensor to detect sound or voice. When a sound is detected, the circuit activates the switch output (turning a connected light or device on). After a pre-set delay period with no further sound, the module automatically switches the output off — providing fully hands-free, automated control.

Q: What voltage does this sound-activated switch module require?

A: This module operates on DC 3V to 9V, making it versatile for battery-powered projects, USB-powered circuits, and a wide variety of DIY electronics applications.

Q: Can I use this module for multiple units in a larger project?

A: Absolutely! The module is available in packs of 1, 5, or 10 pieces, making it easy to scale up for larger installations, bulk DIY builds, or electronics prototyping where multiple sound-activated switching points are needed.

Q: Is this module suitable for beginners in electronics?

A: Yes. The compact SMD design requires minimal external components and straightforward wiring, making it accessible for hobbyists, students, and makers at all skill levels.
