LM393 Sound Detection Sensor Module

This module is used to detect different levels of sound. It can be adjusted to a specific sound level (amplitude). When sound is detected, the module output will be high thus enabling a connected device.
It can be used in several applications such as sound recorder, security systems (an alarm is fired when sound is detected), or as a clapping switch (enable/ disable a device by clapping instead of a manual switch). You can connect this module to Arduino, Raspberry Pi and all sorts of electronic devices and make your own smart application.
