SparkFun ToF Range Finder Sensor – VL6180 測距儀傳感器 超高精度 低噪音 取代 Sharp 傳感器

SparkFun ToF Range Finder Sensor – VL6180 測距儀傳感器 ，與大多數依靠反射光強度或反射角度來確定範圍的距離傳感器不同，VL6180使用精確的時鐘來測量光從表面反彈所需的時間。與其他方法相比，這為ToF測距儀和VL6180帶來了很大的好處，因為它可以更加精確並且對噪聲具有更好的免疫力。這個技術聽起來很熟悉嗎？好吧，這與手機用來檢測呼叫者何時將手機放在耳邊的方式相同。

意法半導體（STMicroelectronics）的VL6180實際上是3合1封裝，將紅外發射器，距離傳感器和環境光傳感器結合在一起，使您可以輕鬆地通過I ² C接口使用和進行通信。ToF Range Finder與突破表親非常相似，但有一些重要區別。使該板與眾不同的是，該傳感器配備了一個板載2.8V穩壓器，這意味著，如果要插入高於2.8V的電壓，它將向下移位，而不必擔心損壞板！還要注意的另一件事是傳感器本身的外形尺寸。許多小型機器人平台都集成了用於長期喜歡的Sharp IR傳感器系列的孔模式。這使得VL6180傳感器幾乎可以替代大多數Sharp傳感器。

注意：儘管數據表中指出VL6180的絕對距離可達10厘米，但我們已經成功測試了25厘米。你知道的越多。

SparkFun ToF Range Finder Sensor – VL6180

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 from STMicroelectronics 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.
