Key benefits Soundactivated output with automatic 10second shutoff: triggers when it detects sound and automatically turns the output off after a 10 s delay, so you get a predictable, hands response without continuous manual control. power direct drive: builtin transistor output can directly drive small motors or power LEDs, eliminating the need for an external driver. Maximum current capacity: 1.5 A. Wide, flexible power options: accepts 3–9 V supply voltage — can be powered by two dry cells or a 5 V power bank for easy mobile or batterypowered use. Stable operation in real environments: builtin antiinterference circuit reduces false triggers from electrical interference caused by motors and other loads (except noise). What it does and how it solves problems Function: detects sound, closes the output, and releases the output automatically after a fixed 10second delay. This provides a simple, repeatable soundtopower control for small loads. Compatibility: works with devices and projects that operate within 3–9 V and draw up to 1.5 A. Directly drives DC motors and power LEDs without additional driver hardware. Reliability: the antiinterference circuit prevents misoperation caused by motor/backEMF or other electrical interference, improving stability in robotics, toys, and small machines. Key attributes Output type: power transistor output, directdrive capable. Maximum output current: 1.5 A. Supply voltage: 3–9 V (supports two dry batteries or a 5 V power bank). Trigger: soundactivated, with an automatic 10 s off delay. Interference handling: builtin antiinterference circuit; will not misoperate due to the interference of motor and (except noise). Practical applications DIY soundactivated lighting: use the module to turn power LEDs on for 10 seconds when a sound is detected, ideal for temporary indication or accent lighting in portable projects. Small motor control for toys and projects: trigger a motor (for example in a simple toy or mechanical display) by sound without adding a separate driver, up to 1.5 A. Interactive prototypes and alarms: add a soundtriggered output to prototypes, art installations, or alarm indicators where a brief, timed motor or LED response is required. Basic usage tips Ensure your load does not exceed 1.5 A and operates within the 3–9 V supply range. For portable setups, use two dry batteries or a 5 V power bank as convenient power sources. Place the module away from strong ambient noise if you want to avoid frequent triggering from environmental sounds. This module provides a compact, reliable way to convert audible events into a timed power output for motors and LEDs, with straightforward power options and builtin protection against electrical interference.
