Arduino Sound Impact Sensor Unit - Digital Output with Amplifying Function

Description:

This Sound Impact Sensor uses a small microphone and amplifier to detect sound. When the loudness — decibel level — of the sound exceeds a preset level, the output of the sensor goes from LOW (0 volts) to HIGH (5 volts).

A small trimmer control lets user adjust the sensitivity of the sensor. Setting this control has the effect of decreasing or increasing the effective range of the sensor, and its overall sensitivity to quieter sound levels. Initially set the control to its mid point, then dial clockwise or counterclockwise to adjust sensitivity:

* Dial clockwise to decrease sensitivity  — quieter sounds not detected. Use this setting in environments where there is a higher amount of ambient (natural) noise.
* Dial counterclockwise to increase sensitivity  — quieter sounds detected.

Features:

* Power requirements: 5 VDC
* Detects sound up to 10 feet away
* Adjustable sound sensitivity control
* Simple digital output indicates if sound has been detected
* PCB Measurement: 31.75 * 17.27mm
