DIYables Sound Sensor Sound Detector for Arduino, ESP32, ESP8266, Raspberry Pi, 2 pieces
Click to zoom
Quick Overview
This DIYables sound sensor sound detector module detects ambient sound intensity and provides a digital output signal (LOW/HIGH) for Arduino, ESP32, ESP8266, and Raspberry Pi projects. The module features a built-in potentiometer for adjusting the trigger threshold, allowing customization of sensitivity to different sound levels.
The sensor outputs a digital signal that changes state when ambient sound exceeds the set threshold, making it ideal for sound-activated projects. The adjustable sensitivity allows fine-tuning for various environments, from quiet rooms to noisy industrial settings.
Perfect for clap switches, voice-activated lights, sound-activated alarms, noise level monitoring, interactive audio projects, smart home automation, security systems with sound detection, and any project requiring audio triggering or ambient noise detection.
