Description LM393 Sound Sensor

The LM393 Sound Sensor is a high-quality module for Arduino. It is designed to detect sound levels. This is done via a sensitive microphone. When the sound exceeds a set threshold, the sensor activates. The core of this module is the LM393 op-amp. This converts sound into a usable electrical signal.

The sensor works like a switch. It reacts to sounds above a certain sensitivity. It can serve as a clap sensor or noise detector. It gives a signal when high sound levels are detected. This property makes it versatile in use.

The device is easy to install. It has a mounting hole for attachment. The sensor works with a voltage between 3.3 and 5V. This makes it compatible with many systems. The digital output is useful for various applications. The signal light indicates when sound is detected. This contributes to the ease of use.
