描述
Grove – IR Distance Interrupter v1.2 紅外線距離感測器
該產品提供了高靈敏度的 RFR-359F 光反射器，使用Grove-紅外傳感器v1.2來檢測是否有物體出現在它的前面。光反射器由GaAs激光發光二極管和硅平面光電晶體管組成。 當物體放置在傳感器前面時，從發射器發出的反射紅外光將被光電晶體管拾取，然後根據反射表面和傳感器之間的距離輸出邏輯高或邏輯低電平。其通過調整電位器來工作，如果反射面是一張白紙，則可以將檢測閾值設置在約90mm至300mm的範圍內。且指示燈則用於顯示測量結果，因爲當檢測到物體時它將亮起亮紅色，反之當沒有任何物體時則熄滅。

原廠文件與範例說明
Provided a high-sensitivity RFR-359F photo-reflector, Grove – IR Distance Interrupter v1.2 can be used to detect if there is an object presenting in front of it. The photo-reflector consists of a GaAs infared light emitting diode and a silicon planar phototransistor. When an object is placed right in front of the sensor, the reflective infrared light emitted from the emitter will be picked up by phototransistor and then outputs logical HIGH or logical LOW according to the distance between the reflection surface and the sensor. By adjusting the potentiometer, you can set the detection threshold value in a range from about 90mm to 300mm if the reflection surface is a piece of white paper. An indicator LED is used to visualize the result of measurement as it will lights up bright red when an object is detected, and go off when there is nothing.
