In this illustration we will going to wire the Infrared distance switch, a high-sensitive photoreflector to detect distance function, ranging from 3cm to 80cm. When the infrared emitted by the emitter it will get reflected on a surface blocked it then the phototransistor will pick up the signal for a distance calculation. This device has integrated with potentiometer to adjust the range for easy and clear to use. Best usage on this device is for robotics, interactive media, industrial and automotive, etc.

As you can see the diagram above the technology behind this effective distance sensor is the modulation from the infrared light, the receiver functionality is sense only if infrared light and only when it receives the correct signal. Therefore it is not very sensitive to ambient light compared to normal infrared detectors. Below are the wiring diagram for testing and how to use this device with Arduino MCU.

    Hi, the 10K resistor in SERIES with the sensor output in the schematic, IS NOT a pullup resistor.

    You need to remove it AND read your own Type1 and Type2 table information and see how to fit the proper pullup.

    OR

    You need to remove it and turn the pullup resistor on in the Arduino software.
