Sound Sensor is a sensor module based on MIC sound sensing element. Sound Sensor is particularly sensitive to sound intensity, and it can be used to detect ambient sound level, but it can not identify the size of sound and the specific sound frequencies. It is available to make voice switches and other works.
3 pins electronic building block interface: input5V - GND, S for detection pin
Parameter:
- Operating voltage:
- Adjustable sensitivity (shown in blue digital potentiometer adjustment)
- With signal LED (if the signal output, the LED will be on)
- Output type: Digital switching output 0-1(If detect sound, output “1”, and the signal LED will be on )
