Provided a high-sensitivity ITR9909 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.

提供了一種高靈敏度RFR-359F光反射器,林 - 紅外距離滅弧1.2可用於檢測是否存在一個物體在它前面的呈遞。光反射器包括在GaAs紅外線的發光二極管和一個矽平面光電晶體管。當對象是正確的在傳感器的前面放置,從發射器發射的反射的紅外光將由光電晶體管被拾起,然後根據反射面和傳感器之間的距離輸出邏輯高或邏輯低。
通過調節電位器,可以在一個範圍為約90毫米到300mm如果反射表面是一張白紙設定檢測閾值。一個LED指示燈用於可視化測量的結果,因為它會亮起檢測到物體時,鮮豔的紅色,和熄滅的時候沒有什麼。
