## Overview

The KY-037 is a compact, high-sensitivity sound detection sensor module featuring an LM393 chip and electret condenser microphone. Operating on a stable 4-6V DC power supply, it offers both analog and digital outputs with an adjustable threshold via potentiometer. Ideal for Arduino DIY kits and smart robot cars, this pack of five modules enables precise acoustic control and sound-triggered automation.

## Description

KY-037 sound detection module has two outputs, AO analogue output which gives real-time output voltage signal of the microphone and DO output when the sound intensity reaches a certain threshold, the output high and low signal. The threshold sensitivity can be adjusted via potentiometer on the sensor. Features: 100% Brand New. Size:32mm*17mm*8mm(length*width*height) Main chip: LM393, Electret condenser microphone. Working voltage: DC 4-6 V. Signal output indication Single channel signal output The output effective signal is low level When there is sound, outputs low level and the signal light Can be used for Acoustic control light , give sound and light alarm working with Photosensitive sensor ,and sound control, sound detect Circuit board output switch quantity Note: The maximum induction distance is 0.5. Package includes: 5 x microphone sensor detection modules.

Review: Work fantastically - Exactly what I wanted
Review: Not as good has I thought it would be. - I found the product OK, but it seems to pick up vibrations of a voice and not the voice alone. It's a pity as it's such a good price.
