Ks0120 keyestudio EASY plug Infrared Obstacle Avoidance Sensor
Introduction
Infrared obstacle avoidance sensor is equipped with distance adjustment function and is especially designed for wheeled robots.
This sensor has strong adaptability to ambient light and is of high precision. It has a pair of infrared transmitting and receiving tube.
When infrared ray launched by the transmitting tube encounters an obstacle (its reflector), the infrared ray is reflected to the receiving tube, after a comparator circuit processing, the indicator will light up.
You can adjust the detection distance by rotating the potentiometer knob, the effective distance range of 2~40cm.
They can be widely used in robot obstacle avoidance, avoidance car, line count, and black and white line tracking and many other occasions.
Note: this module should be used together with EASY plug control board.

Connect It Up
Connect the EASY Plug obstacle detector sensor and LED module to control board using RJ11 cables. Then connect the control board to your PC with a USB cable.
Test Code
Below is an example code. Open or drag below code to Mixly Blocks and upload.
What You Should See
Done uploading the code, when the sensor detects an obstacle, the led is turned on.
Controlling Motor
In the previous section, we use the obstacle detector sensor to control the LED on and off. Now, let’s try another play, controlling the motor rotating.
Hookup Guide
Test Code
What You Should See
Done uploading the code, when the sensor detects an obstacle, the fan motor rotates. Otherwise, fan motor stops.
Troubleshooting:
- Compiling Fails ?
This happens sometimes, the most likely case is a library file not added. You should be sure that all the libraries are added to the libraries directory of Arduino-1.8.5. Shown below.
- Program Not Uploading?
This happens sometimes, the most likely case is a confused Board and serial port, you should firstly select your proper board and port.
