Short Description
The KY-037 "Big Sound" Sensor Module detects sounds using a microphone and is intended for use with Arduino and other microcontrollers.
It detects sound using an electret condenser microphone and generates both analogue and digital signals.
The onboard potentiometer allows you to change the digital detection threshold, making it ideal for clap detection, sound-triggered switches, and noise detection applications.
