Treedix 5pcs Sound Microphone Sensor Detection Module Compatible with Arduino AVR PIC

Features:· The sound module is most sensitive to the ambient sound intensity, and is generally used to detect the sound intensity of the surrounding environment.· When the ambient sound intensity does not reach the set threshold, OUT outputs a high level. When the ambient ambient sound intensity exceeds the set threshold, the module OUT outputs a low level.· The small board digital output OUT can be directly connected to the single-chip microcomputer, and the high-low level is detected by the single-chip microcomputer, thereby detecting the sound of the environment.· The small board digital output OUT can directly drive the relay module, which can form a voice-activated switch.· It can detect the sound intensity of the surrounding environment. Note: This sensor can only identify the presence or absence of sound (according to the principle of vibration). It cannot identify the volume of the sound or the sound of a specific frequency.
