This IR Unit is an infrared sensing unit designed to detect the infrared light reflected from target objects accurately. It is ideal for a range of projects including object detection, tracking, distance measurement, and automation systems.

It generates a voltage value that corresponds to the intensity of the infrared signals reflected by obstacles. Additionally, it includes an LM393 comparator that transforms analogue signals into reliable digital signals, which aids their processing in digital systems.

The unit has an LED indicator, which provides digital control and provides intuitive feedback on the sensor's sensing state. This allows you to ascertain the operational status of the system, which is particularly useful in laboratory settings or engineering projects where timely problem detection and adjustments are critical. It includes a 10k adjustable potentiometer, making it possible for you to fine-tune the sensor's sensitivity and threshold according to different environments and specific needs.


  • Infrared sensing technology: The use of advanced infrared technology can efficiently and accurately detect the reflected infrared light of the target object.
  • Analogue signal output: Through the infrared receiving tube and 10k resistor voltage division, the corresponding voltage value is generated according to the intensity of the infrared signal reflected by the obstacle.
  • Digital signal output: Integrated LM393 comparator converts analogue signals into reliable digital signals for easy processing and interpretation in digital systems.
  • LED indicator: digital signal control LED indicator, intuitive display sensor detection status, users can quickly understand the system operation.
  • Adjustable potentiometer: Equipped with a 10k adjustable potentiometer, users can optimize sensor performance by adjusting sensitivity and threshold to adapt to different environments and application needs.
  • Programming platform: Arduino, UIFlow, etc
