KEYES LM386 Microphone Sound Detection Module with Pin Interface

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
The KEYES Microphone Sound Detection Module is a compact microphone module based on the LM386, a low voltage audio amplifier. The module is designed to capture sound using the built in microphone and amplify the weak microphone signal so it can be used with an Arduino or other microcontroller.

The microphone signal is processed by the LM386 and is available as an amplified signal at the module output. The module can therefore be used in projects for detecting sound, speech, clapping, tapping or other audio events.

The module has a simple pin interface and is easy to connect to a development board. VCC is connected to a 5 V power supply and GND to ground. OUT provides the amplified audio signal and can be connected to an analog input on a microcontroller for further processing.

The LM386 is an audio amplifier and the module provides an analog audio signal. It should therefore be distinguished from sound sensor modules that have a separate digital comparator output. To measure sound level, the signal can be analyzed by a microcontroller and its amplitude or variation over time can be calculated.

The module includes mounting holes and connection wires, making it suitable for prototypes, experiments and various electronic projects.
