Details

The sound sensor has a built-in capacitive electret microphone which is highly sensitive to sound. Sound waves cause the thin film of the electret to vibrate and then the capacitance changes, thus producing the corresponding changed voltage. Since the voltage change is extremely weak, it needs to be amplified. So it is converted into a voltage ranging from 0 to 5V, which is received by data acquisition unit after A/D adapter conversion and then sent to an MCU.

  • Can only detect if there is a sound, which reach the threshold setup by the adjustable resistor, can´t detect the size or frequency of the sound.
  • Based on the microphone and LM358 IC
  • Working voltage: DC 4-6V
  • Signal indicator LED
  • Digital signal output
  • Output right signal as Low TTL (LED On)
  • Could be used for a sound control light, light alarm, light control and light detection

Application:

The module can be applied to noise monitoring in traffic artery, and detection of noises within the boundary of industrial enterprises, factories, and construction sites, detection of noises in urban regions, and noise detection and assessment of living surroundings.
