Sound Detection Sensor Module – Analog Type

Sound Detection Sensor Module – Analog Type detects whether sound has exceeded a threshold value. Sound is detected via microphone and fed into an LM386. The sound level set point is adjusted via an on board potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low.

Features :

• Detectable sound signal size
• Built-in filter-rectifier circuit, DC signal output
• Good sensitivity, built-in amplifier circuit, adjustable gain
• Voltage signal for sound intensity can be obtained by AD conversion
• Analog voltage signal output, signal amplitude VCC/2
• Compatible for Arduino sensor interface.
