Sound Detection Sensor Module
₵15.00
The LM393 Sound Detection Sensor Module for Arduino detects whether the sound has exceeded a threshold value. The sound is detected via a microphone and fed into an LM393 op-amp.
The sound level setpoint is set via an onboard potentiometer. When the sound level exceeds the setpoint, an LED on the module is illuminated and the output is sent low.
