ACROBOTIC 3-Pack IR Infrared Obstacle Detection Sensor Breakout Board for Arduino Raspberry Pi ESP8266 Robot

This breakout board provides a convenient way to use an Infrared (IR) photodiode and photodetector pair for detecting the presence of objects in front of it. The IR transmitter emits light that is able to reach objects in its field of view, and once an object is reached, the light returns to an IR receiver onboard. By measuring the amount of infrared light that is reflected, the module can compare with a preset, adjustable using the built-in potentiometer value, and set the output signal pin either HIGH (no object present) or LOW (object present). The principle of operation of this sensor is straight forward. When the IR transmitter emits radiation, it reaches an object (if present) and some of the radiation reflects back to the IR receiver. Based on the intensity of the reception by the IR receiver, the output of the sensor is set. Note that the transmitter and receiver pair are aimed in parallel to the orientation of the board. Typically, the boards are mounted horizontally relative to the ground plane, so that objects are detected in front of it. I have a separate listing where they are mounted orthogonally to the orientation of the board, which makes it easier to use for lane/line detection, when the objects are underneath the board. Features: Power Supply: 3.3~5VDC This breakout PCB facilitates using an IR transmitter/receiver pair for detecting obstacles, PCB makes the mounting stable, and the soldered output pins facilitate connections to microcontrollers (like Arduino) and single-board computers (like Raspberry Pi) specially using solderless breadboards! Sturdy (1.6mm), blue PCB with a 3-pin header on on side (VCC, GND, DO) 3-Pin header included (pre-soldered!) For useful guides to get you started: https://youtube.com/acrobotic
