I hope you found it useful and informative. N this article I have shown you how the SHARP GP2Y0A21YK0F IR distance sensor works and how you can use it with Arduino. You should get the following output in the serial monitor (Ctrl + Shift +M): Serial monitor output If you want to use multiple IR distance sensors, you can create another sensor object with a different name: SharpIR mySensor2 = SharpIR(IRPin2, model) Note that in that case you also use a different input pin for the second sensor. Note that we have called the sensor ‘mySensor’ in this example. Print the measured distance to the serial monitor: Get a distance measurement and store it as distance_cm: Begin serial communication at a baudrate of 9600: SharpIR mySensor = SharpIR(IRPin, model) Create a new instance of the SharpIR class: Create variable to store the distance: *SHARP GP2Y0A21YK0F IR distance sensor with Arduino and SharpIR library example code. When the beam of light gets reflected by an object, the reflected beam will reach the light detector and an ‘optical spot’ will form on the PSD. The sensor consists of an IR LED and a light detector or PSD (Position Sensing Device). The distance is calculated using triangulation of the beam of light. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to products on .Īn IR distance sensor uses a beam of infrared light to reflect off an object to measure its distance. How to use a SHARP GP2Y0A710K0F IR Distance Sensor with Arduino.

Waterproof JSN-SR04T Ultrasonic Distance Sensor with Arduino Tutorial.

How to use an HC-SR04 Ultrasonic Distance Sensor with Arduino.

In the articles below I explain how these distance/proximity sensors work and how you can use them with Arduino. If you are looking for a more affordable or waterproof distance sensor, take a look at the HC-SR04 or JSN-SR04T.

I have included a wiring diagram and example code so you can start experimenting with your sensor. In this tutorial, you will learn how the sensor works and how to use it with Arduino.

It is a great sensor to use for autonomous robots or non-contact optical switches. The SHARP GP2Y0A21YK0F is an easy to use IR distance sensor with a range of 10 – 80 cm.
