DIYables Analog Sound Sensor Sound Detector for Arduino, ESP32, ESP8266, Raspberry Pi

Quick Overview

The DIYables analog sound sensor is a versatile sound detection module that measures ambient sound intensity. It provides both analog and digital outputs, making it suitable for a wide range of audio-sensing applications.

The analog output gives a continuous reading of sound levels, while the digital output triggers when the sound exceeds a threshold set via the onboard potentiometer. This dual-output design makes the sensor useful for sound-activated projects, noise monitoring, clap switches, and voice-controlled applications.

Key Features

Dual Output — Both analog and digital (HIGH/LOW) outputs for flexible integration
Adjustable Threshold — Built-in potentiometer for setting digital output trigger level
Ambient Sound Detection — Measures the intensity of surrounding sound
Wide Voltage Range — Compatible with both 3.3V and 5V microcontrollers
Presoldered and Not Soldered Options — Provided in presoldered and not soldered versions for selection
Tutorial Support — Extensive tutorials and example code available
...NOTE
If you are using the ESP32, you need to configure the ADC with 11 dB attenuation to set the voltage reference range to handle up to 3.3V.
