Description
The LM393 Sound Detection Module is a sensitive audio sensor that detects sound intensity and outputs a signal when a threshold is exceeded. Using an electret microphone and the LM393 comparator chip, this module can trigger events such as lights, motors, or alarms based on surrounding noise or sound levels.
Perfect for DIY electronics, automation, and sound-reactive projects, it works easily with Arduino, ESP32, Raspberry Pi, and other microcontroller platforms.
