Easy to integrate

Plug and play with my Arduino Uno. The pinout is clearly labeled. Great for prototyping sound-activated projects.

Solid component

Great for prototypes. I used it for a whistle-activated switch idea and it responded instantly. Build quality is decent for hobby electronics.

Good value

Works well for the price. Had to spend some time tuning the potentiometer to get the threshold right, but once set, it is stable.

Sensitivity tricky

Had to adjust the screw multiple times. It picks up a lot of ambient noise if not calibrated carefully. Works okay once configured.

Perfect for Clap Switch

Very responsive module. I used it to build a clap-activated LED strip for my desk. The sensitivity adjustment works well to filter out background noise.

5 FAQ

Q: How do I wire this to a microcontroller?

A: Connect VCC to 5V, GND to Ground, and DO (Digital Output) to any digital input pin on your board.

Q: Does this come with a code library?

A: No library is included. It functions as a standard digital or analog input device, so basic IO code is sufficient.

Q: Is this module weatherproof for outdoor use?

A: No, the PCB and components are not sealed. It should be used indoors or in a protected enclosure.

Q: Can this detect specific voice commands?

A: No, this module detects sound intensity levels only. It cannot process specific voice patterns or commands.

Q: What is the maximum voltage this module can handle?

A: We recommend operating between 3.3V and 5V DC. Exceeding 5V may damage the comparator chip.
