Aktronics® Sound Sensor Module Mic Microphone Sensor High Sensitivity Sound Detection Module Compatible with Arduino PIC AVR (Pack of 5)

Description

AktronicsGreat Sensors for Arduino Project. Having Fun With Electronics and Programming!Description:The Sound Detector is based on a microphone and a power amplifier. It can be used for detecting the sound strength of the environment.This sound sensor gets signal by both digital and analog output."AO" outputs real-time voltage signal of the microphone."DO" outputs low and high lever signal when the sound intensity reaches a threshold.Sensitivity is adjustable by adjusting the potentiometer.PCB-mounted LEDs indicate the power and compactor output.Wiring Instructions:+ ---- DC 3.3V-5.5VG ---- GroundingAO ---- Analog OutputDO ---- Digital Output.Specification:Model: KY-037Working Voltage: DC 3.3V-5.5VNominal Frequency: 40KHzPCB Size: 35 x 15mm / 1.38" x 0.59" (L*W)Fixed Hole Diameter: 3mm
