# Ultrasound and Sound Module

![](https://kittenbothk.readthedocs.io/en/latest/_images/06_04.png)

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.

### Details

### Specifications

* Voltage: 3V-5V
* Dimensions: 56mm X 24mm X 16mm
* Connector: 4Pin PH2.0
* Ultrasound Detection Range: 4cm-200cm(Recommended)
* Analog Return Value Range: 0-1023

### Precautions

* 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.
