LM393 Sound Detection Sensor Module
The LM393 Sound Detection Sensor Module, designed for compatibility with Arduino, is engineered to detect sound levels above a specific threshold. It uses a microphone to capture sound and an LM393 operational amplifier to process the signal. The module includes an adjustable potentiometer, allowing users to customize sensitivity according to their requirements. When the sound level surpasses the set threshold, the module’s LED illuminates, and it outputs a low signal as an alert.
Features
- Signal output indication.
- The output is digital.
- Single-channel signal output.
- With the retaining bolt hole, convenient installation.
- Output low level and the signal light when there is sound.
