Product Description

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

Specification :

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)
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.
