BASIC ELECTRONICS PROJECT 6- MAKING AN IR SENSOR

Hi..friends ,welcome back……!! This time I am here with some discussion on INFRA RED sensors. IR sensors are most widely used in many electronics and robotics project , so have a look how to make a IR sensors and how to use them.??

INTRODUCTION

IR SENSORS circuit is very important circuit to detect the presence of any object or to distinguish between black and white colors these sensors are most widely used in making a black or white line follower robots. IR emitter detector circuit is very easy to implement and it can be easily used in object detection, motion detection or color sensing.

IR reflective sensors have emitter (IR LED) and receiver (Photo‐Transistor or photo diode). If white surface is present beneath the IR LED or if there is any object, IR rays are reflected and are sensed by the receiver, while in case of no object receiver does not sense IR rays and same is in case of black surface as light gets absorbed and hence receiver does not sense IR rays.

IR SENSOR CIRCUIT 

Here is the circuit which we have to implement for making our IR sensor module just implement circuit and calibrate your circuit with the help of variable resistor for proper result.

now this sensor circuit can be used in so many electronics and robotics projects. In our other posts we will discuss about use of IR sensors in so many projects.

For making a line follower robot with IR sensors just go to this link   ROBOTICS PROJECT 1- MAKING A LINE FOLLOWER ROBOT WITHOUT USING MICROCONTROLLER

I hope this article was useful for you guys..!! 

In case of any doubt, query or critical view just leave a comment. I am waiting for your comments.
