produce a heating effect. Though the sun emits all of the different kinds of electromagnetic radiation‚ 99% of its rays are in the form of visible light‚ ultraviolet rays‚ and infrared rays (also known as heat). Radiation from the Sun‚ which is more popularly known as sunlight‚ is a mixture of electromagnetic waves ranging from infrared (IR) to ultraviolet rays (UV). It of course includes visible light‚ which is in between IR and UV in the electromagnetic spectrum. The Sun does not only produce IR‚ visible

the sensor can be mounted to a servo to allow it to rotate. Figure 2 below shows a robot that utilizes such a setup. LINE FOLLOWER A line tracker mostly consists of an infrared light sensor and an infrared LED. It functions by illuminating a surface with infrared light; the sensor then picks up the reflected infrared radiation and‚ based on its intensity‚ determines the reflectivity of the surface in question. Lightly colored surfaces will reflect more light than dark surfaces; therefore‚

It receives the signals from the sensors‚ and this signal is operated under the control of software which is stored in ROM. Microcontroller AT89S52 continuously monitor the Infrared Receivers‚ When any object pass through the IR Receiver’s then the IR Rays falling on the receiver are obstructed ‚ this obstruction is sensed by the Microcontroller CHAPTER :- 2 BLOCK DIAGRAM AND ITS DESCRIPTION 2.1 Basic Block Diagram

Herschel discovered infrared light when he was observing the sun he noticed that when he put coloured filters over his telescope that different coloured filters heated up his telescope by different amounts. Using a prism he broke up visible light he put a thermometer in the different colours. He found that the temperature got more massive as he moved the thermometer from violet to red after this He then measured the temperature where there was no visible light ( red end of the spectrum) and it was

Preparation of Bromotriphenylmethane Abstract The structure of a major component of star anise oil was derived by analyzing its IR spectroscopy melting point of after oxidation and purification. From the evidence obtained‚ it was concluded that the exact structured should be p-methoxybenzoic acid. Introduction The purpose of this experiment is to determine the structure of the major component of star anise oil. It is already known that this component has a molecular formula C10H12O. This
