KEYES High Sensitivity Microphone Sound Detection Module Sound Control Sensor Compatible with Microb

Feature:

This is a commonly used sound detection sensor, which mainly uses a high-sensitivity microphone element and LM386 chip. High-sensitivity microphone components are used to detect external sounds. Using the LM386 chip to build a suitable circuit, we amplify the sound detected by the high-sensitivity microphone, and the maximum multiple is 200 times. When using, we can adjust the sound magnification by rotating the potentiometer on the sensor. When adjusting, adjust the potentiometer clockwise to the end to maximize the magnification. This module is compatible with various microcontroller control boards.

The module is an anti-reverse insertion white terminal with a pitch of 2.54mm. When in use, we can use DuPont cable to connect to the microcontroller. For the convenience of wiring, we also specially designed an expansion board which is fully compatible with this module and UNO R3 microcontroller.
