Description
LM393 Sound Detection Sensor
Sound Detection Sensor Module provides an easy way to detect sound and is generally used for detecting sound intensity. This module can be used for security, switch, and monitoring applications. Its accuracy can be easily adjusted for the convenience of usage. It uses a microphone that supplies the input to an amplifier, peak detector, and buffer. When the sensor detects a sound, it processes an output signal voltage which is sent to a microcontroller then performs necessary processing.
Features/Specs:
- Operating voltage 3.3V-5V
- Outputs digital switching output (high and low level 0 and 1
- Operating current (Vcc=5V): 4-8mA
