IR Proximity Sensor

The IR Proximity Sensor module has great adaptive capability of the ambient light, having a pair of infrared transmitter and the receiver tube, the infrared emitting tube to emit a certain frequency, encounters an obstacle detection direction (reflecting surface), infrared reflected back to the receiver tube receiving, after a comparator circuit processing, the green LED lights up, while the signal output will output digital signal (a low-level signal), through the potentiometer knob to adjust the detection distance, the effective distance range 2 ~ 30cm working voltage of 3.3V-5V.

The detection range of the infrared proximity sensor can be adjusted by the potentiometer, with little interference, easy to assemble, easy to use features, can be widely used for line follower robot ,obstacle avoidance, DIY Automatic Sanitizer Dispenser Kit, obstacle avoidance car assembly line count and black-and-white line tracking, and many other occasions.


  • Easy to assemble and use

1. What is an IR Sensor and why is it not visible?

  • An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Infrared radiation was accidentally discovered by an astronomer named William Herchel in 1800. While measuring the temperature of each color of the light (separated by a prism), he noticed that the temperature just beyond the red light was the highest. IR is invisible to the human eye, as its wavelength is longer than that of visible light. Anything that emits heat gives off infrared radiation

2. What are the types of IR sensor and their difference?

  • There are two types of infrared sensors: active and passive.
    • Active infrared sensors both emit and detect infrared radiation.
    • Passive infrared (PIR) sensors only detect infrared radiation and do not emit it.

3. What is the difference between PIR and IR Sensor?

  • The IR sensors detect whether the light from the transmitter is emitted by an object or a person. Whereas, the PIR sensors detect changes in the levels of energy around the area.
  • If the PIR sensor is installed towards the changing environment, it may let off a false alarm due to the change in the way the air flows; however, IR sensors must be installed facing the motion. 
  • IR sensors are usually only installed on the outside of properties, whereas PIR sensors are usually installed inside.
  • PIR sensors don't actually emit the infrared; objects give the sensor infrared rays. This differs from IR sensors, which do actually infrared.
