1. Introduction The Sound Sensor Module is designed to use as a sound/audio detection. This sensor module can only detect the present of sound/audio, but not to differentiate the sound’s level. User may use it to detect sound and further determine whether human or animal is present in a room. There is only digital output. Sensitivity of sensor module can be adjusted through the adjustor on the module. Specification:  Input Voltage: DC 3.3V to 5V  Output: Digital
