The Sound sensor is able to detect different sizes of sound. This sensor can be used to for a variety of uses from industrial to simple hobby or playing around.
These little units can sense sound and variations in sound and interface easily with microcontrollers. When the ambient sound levels are less than the threshold set by the potentiometer, the output of the unit is High, conversely when the ambient sound levels rise above the pre-set threshold, the modules output is Low.
Output in the form of digital switching outputs (0 and 1 high and low)
