Package : SMDis_customized : YesModel Number : KY-037Operating Temperature : 11Dissipation Power : 5vSupply Voltage : KY-037Application : AlarmCondition : NewType : Voltage RegulatorBrand Name : baishundianzi : Mainland ChinaFor sound detection module has two outputs:1. AO, analog output, real-time output voltage signal of the microphone2. DO, when the sound intensity reaches a certain threshold, the output high and ?low signalModule features:1. there is a mounting screw hole 3mm2. the use 5v DC power supply3. with analog output4. there are threshold level output flip5. high sensitive microphone and high sensitivity.6. a power indicator light7. the comparator output is lightDigital Output:int Led=13;/define LED ?interfaceint onpin=3 /Define D0 Sensor ?
