# Distance Sensor
![](img/DistanceSensor03.jpg)

## **Introduction**
<font style="color:rgb(44, 44, 54);">The distance sensor detects the distance between objects and the sensor, with a detection range of 0~255 cm.  </font>

<font style="color:rgba(0, 0, 0, 0.85);">Using laser reflection principles, the sensor measures the round-trip time of laser signals to calculate the absolute distance between the sensor and the target. The sensor emits laser at a wavelength of 940 nm and completes distance measurements up to 2 meters in under 30 ms.  </font>
