Description
One sound microphone sensor module. It is most sensitive to the intensity of ambient sound. When sound stays below the set threshold, the OUT pin holds high. When sound passes the threshold, OUT drops low, so a microcontroller can read it directly or drive a relay as a sound-controlled switch.
This listing is for one single module. Quantity 1.
- Function: ambient sound intensity detection
- Working voltage: 3.3V to 5V
- Output: digital switch output, OUT pin, high and low levels
- Sensitivity adjustable with the onboard potentiometer
- Board size: 32mm by 17mm, with fixing bolt holes
- Pins: VCC, GND, OUT
In the box: 1 sound microphone sensor module.
