5V noise/sound sensor with potentiometer for Arduino AVR, 2.54 mm

5V noise and sound sensor with potentiometer

The sound and noise sensor module is a versatile solution compatible with popular microcontroller platforms. It works excellently as an add-on for Arduino, for ESP8266, for ESP32, and for Raspberry Pi. The device features a built-in condenser microphone and a precise potentiometer for sensitivity adjustment.

The sensor allows registering a defined noise level from the environment or detecting loud, sudden sounds such as a clap. The sensor is powered by 5V and has a digital output, which greatly simplifies its use. The module’s compact dimensions of just 32 mm x 15 mm allow trouble-free integration in a wide range of electronic projects.
