The Sound Detector is a sensor module containing a microphone and a power amplifier. It can be used for detecting the sound strength of the environment. The sensitivity of the digital output can be adjusted by the potentiometer. Analog output is also available.
The Sound Detector has two outputs:
AO - Analog output, real-time output of the microphone signal.
DO - When sound intensity is below a pre-defined threshold, the output is low. When sound intensity raises above that threshold, the output is high. The threshold (sensitivity) can be adjusted via the potentiometer on the sensor.
