Reliable clap switch component

I built a clap-switch for my lamp using this sensor. It responds instantly to claps and ignores constant humming noises. The digital output is clean and stable.

Excellent sensitivity range

Impressed by how well this picks up quiet sounds when turned up, yet handles loud noises without saturating immediately. A must-have for any electronics hobbyist.

Good quality, easy to use

The build quality is solid and the red PCB looks nice. It took a minute to dial in the potentiometer for my specific room environment, but once set, it triggers reliably.

Great for school robotics

Used this for a sound-following robot project. The analog output gives great range for measuring sound intensity, not just on/off detection. Highly recommended for students.

Solid performance

Works as described. The only minor issue is that the pin headers were not pre-soldered, but that's standard for these modules. Easy to integrate into existing code.

Perfect for voice-activated projects

This module works flawlessly with my Arduino Uno. The sensitivity adjustment is very precise, allowing me to filter out background noise effectively. Great value for the price.

5 FAQ

Q: Does this module output audio signals or just detection levels?

A: This module outputs detection levels via Digital (high/low) and Analog (voltage proportional to sound intensity) signals. It does not output raw audio waves suitable for recording.

Q: What is the maximum effective distance for sound detection?

A: The effective range depends on the sound volume and your sensitivity setting. Typically, it can detect normal speech or clapping from 2 to 5 meters away when adjusted correctly.

Q: Can I power this directly from a 5V USB port?

A: Yes, the module operates within a 3.3V to 5V range, so connecting it to a standard 5V USB power source is perfectly safe and recommended.

Q: Is the analog output linear with sound pressure?

A: The analog output voltage increases with sound intensity, providing a relative measure. While generally responsive, it is calibrated for detection logic rather than precise scientific decibel measurement.

Q: Do I need any external libraries to use this with Arduino?

A: No external libraries are required. You can read the digital pin using standard digitalRead() and the analog pin using analogRead() functions in the Arduino IDE.
