IR spectrum can divide into three regions namely near-infrared, mid and far-infrared region. The range of these waves is between 0.7 micrometers and 100 micrometers. In the electromagnetic spectrum, IR radiations lie in the visible and microwave region. Since the IR sensor uses low power that makes them user-friendly and uses widely. For example in the TV remote, IR technology is used for the communication between the TV and it’s remote allowing the user to have a level of comfort by controlling the TV from a fair amount of distance rather than manual labour. IR technology is widely used in industries and our daily life.
Sensors capable of working with that region of light are IR sensors. In order to be able to interface IR sensor with Arduino, it is necessary to understand what IR sensor actually is.
In this tutorial, we’ll interface the IR sensor with Arduino Uno including coding, connection diagram, and listing the components. ( 3) To make Line Following Robot and detection of object, IR sensor is best to use in such situation
