High Sensitivity Sound Microphone Sound module Voice recorder detector For Toys
This sound detection microphone sensor module is ideal for noise detection in alarm systems, home automation and other applications in which an event is triggered based upon the presence or absence of sound. The module features two outputs: DO is a digital output which goes high when sound is detected, and can be connected to a digital input of microcontroller. AO is an analog output that provides a real-time output voltage signal of the microphone. LED1 illuminates when power is applied to the module. LED2 illuminates when sound is detected (i.e. when DO goes high). The sound threshold to trigger DO is adjusted by the on-board potentiometer.
Power supply voltage: +5V Power On LED light: LED1 Electret Condenser Microphone (ECM) sensor AO = analog output provides a real-time output voltage signal of the microphone DO = Digital output, output goes high when the intensity of the sound reaches threshold Comparator Circuit: LM393 Comparator Output LED: LED2, on when sound reaches threshold Built in potentiometer can be used to adjust the DO threshold level Mounting screw hole size: 3mm Circuit Board Dimensions: 35mm x 15mm x 14mm (L x W x H, excluding connector and microphone) Operation: Pin + to +5VDC Pin - to Ground Pin AO to Microcontroller Analog Input (for analog program) Pin DO to Microcontroller Digital Input (for digital program) LED1 will illuminate when power is applied Turn potentiometer counter-clockwise until LED2 turns off. This is the sound threshold. Then adjust to the appropriate threshold for your application.
