Microphone Voice Sound Sensor Module

Sensor-Arduino Small Sound

• Microphone sensor module. can be applied to your projects to sense audio suitable with Arduino, uses a comparator LM292 to achieve digital thresholding contains both digital and analogue outputs.

Specifications:

• 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)
