Description
IR Sensor Module – The IR Infrared Obstacle Avoidance Sensor Module by ADIY has a pair of infrared transmitting and receiving tubes. When the transmitted light waves are reflected back, the reflected IR waves will be received by the receiver tube. The onboard comparator circuitry does the processing and the green indicator LED comes to life.
Application: IR Sensor Module
- Night Vision Devices
- Radiation Thermometers
- Flame Monitors
- Water Analysis

The module features a 3-wire interface with VCC, GND, and an OUT pin on its tail. It works fine with 3v3 to 5V levels. Upon hindrance/reflectance, the output pin gives out a digital signal (a low-level signal). The onboard preset helps to fine-tune the range of operation, effective distance range is 2cm to 10cm.
Pin Configuration: IR Sensor Module
- VCC: 5V external voltage
- GND: Ground
- OUT: Digital output interface (0 and 1)
How it works: IR Sensor Module
The white LED here is an IR LED which works as the transmitter and the component next to the IR LED is a photodiode that works as the receiver in the IR sensor. The IR transmitter continuously emits the IR light and the IR receiver keeps on checking for the reflected light. If the light gets reflected back by hitting any object in front it, the IR receiver receives this light. This way the object is detected in the case of the IR sensor. The blue knob here is a potentiometer. Users can control the range i.e. from how far you want to detect the object by changing the value of the potentiometer. An IR sensor has two small LED indicators – one for power, which is ON the entire time the sensor is ON; the other is the Signal LED which detects the object.
