AJMRTC sound detection sensor module adopts high-sensitivity electret microphone and LM393 comparator chip to capture ambient sound signals and output single-channel switching signal. Users can adjust detection sensitivity through the onboard potentiometer to set trigger volume threshold. The LED indicator lights up once sound exceeds the preset value, convenient for circuit debugging. Powered by DC3.3V-5V, it can be directly connected with Arduino, Raspberry Pi and other microcontrollers. Widely applied for sound-activated switches, noise monitoring, sound alarm, robot and other electronic prototype making.
