Ks0120 keyestudio EASY plug Infrared Obstacle Avoidance Sensor

EASY plug 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.
This module should be used together with EASY plug control board.

Special Note:
The sensor/module is equiped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface.
If you have the control board of other brands, it is also equiped with the RJ11 6P6C interface but have different internal line sequence, can not be used compatibly with our sensor/module.

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.

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.
