SeeedStudio Grove IR Distance Interrupter v1.2

Grove – IR Distance Interrupter v1.2 is provided with high-sensitivity ITR9909 photo-reflector, Grove – IR Distance Interrupter v1.2. The photo-reflector consists of a GaAs infrared 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 light up bright red when an object is detected, and go off when there is nothing.
