1 X Sound Detector Module for Arduino

Sound detection sensor module for arduino detects whether sound has exceeded a threshold value. Sound is detected via microphone and fed into an LM393 op amp. The sound level set point is adjusted via an on board potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low.

  • Sound Sensor Module Sound Detection Module Main Chip: Lm393, Electret Microphone
  • Working Voltage: Dc 4 ~ 6v Has The Signal Output Instructions Single Signal Output.
  • Effective Signal Output For Low Level. Output Low Level And Signal Light Will On When There Has Voice.
  • Can Be Used For Sonic Lamp, With Photosensitive Sensors Act As Sound And Light Alarm, Also Can Be Used In The Occasion Of Voice Control And Sound Detection. Circuit Boards Output Switch Value.
