Parallax Sound Impact Sensor KickStart (#29132)
Please note: This product has been discontinued.
What It Can Do
•
Detects sound up to 10 feet away
•
Adjustable sound sensitivity control
•
Simple digital output indicates if sound has been detected
The 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 you 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.
