Ir Sensor Array Circuit Diagram

This sensor is analogous to humans visionary senses which can be used to detect obstacles and it is one of the common applications in real timethis circuit comprises of the following components.

Ir sensor array circuit diagram. Ir sensor circuit diagram and working principle an infrared sensor circuit is one of the basic and popular sensor module in an electronic device. For the op amp connections have a look at the ckt diagram providedthe conncetion for each op amp is identical. You can make this line follower with 2 sensors 3 sensors and 5 sensors also its your choice. Ir led emits infrared light.

Complete circuit diagram for arduino line follower robot is shown in the above iamge. A typical ir sensing circuit is shown below. Based on the intensity of the reception by the ir receiver the output of the sensor is defined. Obstacle sensing circuit or ir sensor circuit.

If you want to make with 2 sensor line follower robot with arduino go through this. You need small piece of veroboard general purpose pcb. The maze solving robot detects the walls by using the ir sensor module and moves the robot close to the wall until it finds a no wall region. Actually a group of such sensor units as described above is required to make a line follower robot.

Ir sensor work on the principal in which ir led emits ir radiation and photodiode sense that ir radiation. Line follower robot circuit diagram. The output of this sensor will have to be taken from the junction of the photodiode and the 10k resistor which in the circuit diagram given below is connected to the 3rd pin of the ic. And motor drivers input pin 2 7 10 and 15 is connected to arduinos digital pin number 4 5 6 and 7 respectively.

Ir sensor array contain 8 ir led and 8 ir sensor also it have two mode of output. 1 analog output direct analog data from ir sensor 2 digital output using linear voltage comparator with potentiometer. The male header pins are where the output from the ir sensor array is connected and the female header are where the output of the op amp board is connected to the arduino. Digital data the smallest unit of digital data is called a bit.

But in this tutorial we are making it with the 5 sensor module of ir. We generally use 3 or 5 such sensor unit to make a line sensor array. Lets understand the circuit diagram. The array of ir sensors has 2 ir sensors on the left side of the robot two ir sensors on the right side of the robot and one ir sensor in the front of the robot.

As you can see output of comparators is directly connected to arduino digital pin number 2 and 3.
