商品說明

Grove – IR Distance Interrupter V1.2 紅外線距離感測器

提供了高靈敏度的ITR9909光反射器，可以將Grove-IR Distance Interrupter v1.2用於檢測前面是否有物體。光電反射器由GaAs紅外發光二極管和矽平面光電晶體管組成。當將物體放置在傳感器的正前方時，從發射器發出的反射紅外光將被光電晶體管拾取，然後根據反射面與傳感器之間的距離輸出邏輯高或邏輯低。

如果反射面是一張白紙，通過調節電位器，可以將檢測閾值設置在大約90mm至300mm的範圍內。指示燈LED用於可視化測量結果，因為當檢測到物體時，該指示燈會亮紅色，如果沒有物體，該指示燈會熄滅。

Grove – IR Distance Interrupter V1.2

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.
