  • Description
Sound Detector Module (Digital Output)

Digital Sound Detector Sensor Module

The Digital Sound Detector Sensor Module has an on-board potentiometer to adjust sensitivity, the module outputs high when the threshold is reached.

Given that this device measures whether or not sound has exceeded a threshold,  you’re basically left with determining what it is you want to do.   What I mean by this is that you can do something when it is quiet and/or you can do something when it is loud.  For example:

  • You could detect whether or not a motor is running.
  • You could set a threshold on pump sound so that you know whether or not there is cavitation.
  • In the presence of no sound,  you might want to create an ambiance by turning on music.
  • In the presence of no sound and no motion, you may go into an energy savings mode and turn off the lights.

When referring sensititivity,

  • When less sensitive,  it takes more sound to trigger the device
  • When more sensitive, it takes less sound to trigger the device

Characteristics:

Led status indicator
Voltage: 3.3 – 5V
Output: Digital
