About Uxcell Sound Microphone Sensor Detection Module
Great 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 Package Includes:3 x Sound Detection Sensor Module
