displayed on the seven segment displays. The microcontroller does the above job. 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

Remote sensing includes collection of information from a system by either absorbing or scanning EMR which are reflected from the system. This is done without disturbing the actual system under observation

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

certain gases in the atmosphere trap energy from the sun. * Earth receive most of it’s energy‚ called radiation‚ from the Sun sun earth Atmosphere * The Earth’s surface absorbs the solar energy and release it back to the atmosphere as infrared(IR)radiation‚ some of which goes back to space. * IR radiations emitted by the Earth is absorbed by gases in the atmosphere that re-emit the energy as the heat back towards the Earth’s surface.

among other things. By looking at the shape of the spectrum of light emitted by a star‚ we can tell something about its average surface temperature. i) If we observe a star’s spectrum and find that the peak power occurs at the border between red and infrared light‚ what is the approximate surface temperature of the star? (in degrees C) The temperature will be ~4000K which would be about 3276 degrees Celcius. ii) If we observe a stars spectrum and find that the peak power occurs at the border between

Then some of the energy is radiated back into space‚ by the Earth‚ in the form of infrared waves. However during this process‚ some of the outgoing infrared radiation is trapped by the Earth’s atmosphere and warms it; which in return keeps the temperature at a livable and somewhat constant level. However‚ the atmospheric layer is now being thickened by the harmful pollution and because of that more of the infrared waves are being trapped and are now warming more worldwide.

Multistep Synthesis of Tetraphenylcyclopentadienone Author: Instructor: Date work performed: 10.18.2012--10.25.2012 Date work submitted: 11.01.2012 Abstract: The aim of this experiment was to perform a multistep synthesis to form tetraphenylcyclopentadienone. The first step of the reactions was to synthesize benzoin from the condensation of benzaldehyde. A yield of 28.91% benzoin was obtained. The MP of benzoin was 127O-130O C and the IR spectra displayed a carbonyl peak at 3415 cm-1

Greenhouse Effect When one starts a car or burns wood‚ the last thought on their mind is the consequences to these actions. Unfortunately‚ the daily dangers to earth are not widely know. Due to the constant change of society‚ this planet must cope with various problems. One of the most important ecological structures is the ozone layer. The same shield that protects us from the sun ’s deadly radiation‚ can also act as a blanket engulfing us in heat. This situation is know as the greenhouse effect
