The output is digital signal so it is easy to interface with any microcontroller such as Arduino/Genuino UNO, Mega, Leornado, Zero, 101, even the Raspberry Pi or Raspberry Pi Zero. And of course it is also compatible with all other controller boards out there including CIKU, CT-UNO, CT-ARM, etc. This Infrared sensor offers simple, user friendly and fast obstacle detection via infrared reflection, it is non contact detection. As it is based on light reflection, the detection do vary with different surface. And any infrared source might also interfere the detection.
