Description: This is sound detection sensor module board for Arduino base on LM386 amplifier IC. It can output analog value for the voice, and you can adjust the potentiometer clockwise to increase the analog value amplitude. It can also output a HIGH level signal when the analog value is higher than the threshold and you can adjust the potentiometer clockwise to increase the threshold value. The red led onboard will light on when the analog value exceeds the set threshold. Features: -Working voltage: 3.3V-5.3V; -Working current: 100mA(MAX); -Interface: 4PIN, 2.54MM pitch -Active level: High level; -PCB dimensions: 42 x 24mm; -Mounting holes diameter: 2.2mm; -Applications: Ambient sound detection; Voice control lights.
