This module combines ultrasound sensor and a microphone into the same module.
The ultrasound sensor is used to measure the distance of objects, the microphone is used to measure the loudness.
Dimensions: 56mm X 24mm X 16mm
Ultrasound Detection Range: 4cm-200cm(Recommended)
Analog Return Value Range: 0-1023
Ultrasound works better on items with smooth surfaces, the smooth surface should be perpendicular to the module.
Ultrasound emits signal in the shape of an arc, make sure there is no obstacle in the signal range.
The microphone only determines loudness of a sound, it can’t measure decibels. Measuring decibels require professional equipment.
Connecting the module
Connect the Ultrasound Module to Armourbit with a 4Pin cable.
