OVERVIEW
GebraBit Sound Detector module is a Highly-Sensitive microphone integrated with a Voltage Comparator OpAmp.
GebraBit Sound Detector module can operate with “3V3” or “5V” supply Voltages by considered “VCC SEL” jumper selector.
Module OUTPUT is available as the analog and digital voltage on GebraBit Sound Detector module “A0” and “D0” pins.
The sound intensity threshold is adjustable by an embedded potentiometer in the GebraBit Sound Detector module, when the sound intensity goes above, or below the threshold, the “DO” pin and the “Sound Detected” LED status will be changed.
WARNING: FOR ACCURATE INFORMATION ABOUT ICs ABSOLUTE MAXIMUM RATINGS AND ITS PRECIOUS CHARACTERISTICS RANGES, USERS MUST CERTAINLY REFER TO ICs MANUFACTURE DATASHEET.
