LM393 Sound detection sensor module

Description

LM393 Sound Detection Sensor Module for Arduino detects whether the sound has exceeded a threshold value. LM393 comparator for easy integration with mounting holes and pin headers, configurable sensitivity, digital output for sound presence detection, and an LED indicator. It provides accurate sound recognition, programmable sensitivity, and easy integration into a range of projects. A microphone picks up the sound, which is then put into an LM393 op-amp. An inbuilt potentiometer is used to adjust the sound volume setpoint. An LED on the module illuminates and the output is sent low when the sound level exceeds the setpoint.
