IR Proximity Obstacle Avoidance Sensor Module

IR Proximity Obstacle Avoidance Sensor Module - This module uses a pair of infrared emitters and receivers to detect obstacles nearby. The infrared beam reflects on obstacles and illuminates the receiver. There is a small potentiometer on board to adjust the module’s sensitivity. Its range can be adjusted from 2cm to 30 (depending on the reflectiveness of the obstacles), you can feed him 3-5V and the output pin will trigger when it will detect obstacles.


  • Operating Voltage: 3 to 5 V
  • Trigger distance: 2 to 30cm
  • Detection angle: 35°

IR Proximity Obstacle Avoidance Sensor Module – Description

The IR Sensor Module features a pair of infrared tubes to work as transmitters and receivers. Once the transmitted light wave is released, it travels back to the receiving tube situated at the receiving end. Meanwhile, there is an onboard comparator circuitry to do the processing functions that further lit up the green-colored LED indicator.

Furthermore, the IR Proximity Obstacle Avoidance Sensor represents a 3-wire interface mechanism with the integration of Vcc, GND, and an Output Pin. It is supposed to deliver amazing performance with 3.3 to 5V levels. The dedicated output pin reflects a digital signal upon witnessing any type of hindrance. Therefore, the onboard preset assists users in fine-tuning the range of operations. It works effectively within the range of 2cm to 80cm.

Coming with the spectacular adaptive capability of the ambient light, the IR sensor reflects a pair of tubes known as transmitters and receivers. It helps detect an obstacle by emitting a certain frequency in the right direction. The emitted light wave is reflected back to the source to be received by the unit called the receiver tube. Once the comparator processing is over, a green digital LED lights up. At the same time, the signal output will obtain a low-level digital signal. The effective
the distance range is 2-80cm whereas; the ideal working voltage is 3.3V-5V.

The integrated potentiometer is used to adjust the detection range of the sensor. It brings prominent features such as being easy to use, easy to assemble, and can be broadly used as robot obstacle avoidance. Among the 3 wires, the output pin shows a digital signal. Therefore, it has stringent adaptability to the environment and helps clients detect the distance with the help of two tubes.


  • Onboard detection indication
  • Easy to assemble
  • Easy to use
  • Effective distance range – 2cm – 80cm
  • Fine tune distance range through a preset knob
All in all, the IR Proximity Obstacle Avoidance Sensor is quite beneficial across several industries. It helps detect the distance with the help of a transmitter and receiver tube. You will find a pair of tubes that are valuable in performing the whole process while identifying the distance. Further, the detection range of the sensor is evaluated with the help of a potentiometer. It hosts many creative facilities for users, including easy assembling and usage and onboard detection indication. Overall, the IR Sensor is a great package of services one can hold to invigorate projects for improvement.
