Working of Sound Sensor Module

This sensor has three functional components on its board. This is the sensor unit at the front of the module, which physically measures the current environment and outputs it as an analog signal to the second unit, the amplifier. This amplifies the signal depending on the resistor set on the rotational potentiometer and directs it to the analog output of the module. The third unit is a comparator that switches the digital output and the LED when the signal falls below a certain value. By means of the rotary potentiometer, the sensitivity can be adjusted.

 

  • The sensor emits a signal if the front microphone of the sensor perceives a noise.
  • Digital Output: Via the potentiometer, a limit value of the received sound can be set, at which the digital output should switch.
  • Analog Output: Direct Microphone Signal as Voltage Level.
  • Sensitivity is adjustable by the on-board potentiometer.
  • LM393 Comparator is applied to select the Digital Output.
  • Please note that the signal is inverted, if a high value is measure, analog output will result a lower voltage value.
