본 제품은 VL6180칩 기반의 거리 측정 센서 입니다. 반사된 빛의 강도나 각도를 

이용하여 거리를 측정하는 센서와는 다르게 VL6180은 정밀한 클럭을 사용하여 

표면에 반향되어 돌아오는 적외선의 시간을 측정하여 거리를 측정합니다.


VL6180은 IR emitter, 거리센서, 광(빛) 센서가 (3in1) 하나의 패키지로 이루어져있으며

I2C 인터페이스를 통해 통신할 수 있습니다.

2.8V의 레귤레이터가 장착되어 있어, 그 이상의 전압을 공급하여도 망가지지 않습니다.


VL6180의 데이터시트에는 약 10cm 까지 측정이 가능하다고 나와있으나,

테스트 결과 25cm 가량 측정이 가능합니다. 


Description: This is the SparkFun “Time-of-Flight” Range Finder, a sensor board for the VL6180 distance sensor. Unlike most distance sensors that rely on reflected light intensity or reflected angles to determine range, the VL6180 uses a precise clock to measure the time it takes light to bounce back from a surface. This affords the ToF Range Finder and VL6180 a great benefit over other methods because it can be much more accurate and more immune to noise. Does this technology sound familiar? Well it should, it’s the same means cellphones use to detect when the caller is holding their phone to their ear.

The VL6180 is actually a 3-in-1 package that combines an IR emitter, a range sensor, and an ambient light sensor together for you to easily use and communicate with via an I2C interface. The ToF Range Finder is very similar to its breakout cousin with a few important differences. What sets this board apart is this sensor is equipped with an on-board 2.8V regulator, which means if you were to plug in a voltage higher than 2.8V it will be shifted down without worry of damaging your board! Another thing to note is the form factor of the sensor itself. Many small robotics platforms have integrated hole patterns for the long time favorite Sharp IR sensor line. This allows the VL6180 Sensor to be a near drop-in replacement for most Sharp sensors.

Note: Though the datasheet states the VL6180 measures an absolute range of up to 10cm, we have successfully tested it up to 25cm. The more you know.
