The IR transmitter is used to transmit the infrared rays in our eye. The IR receiver is used to receive the reflected infrared rays of eye. If the eye is closed means the output of IR receiver is high otherwise the IR receiver output is low. This to know the eye is closing or opening position. This output is give to logic circuit to

CHAPTER 1 INTRODUCTION The rapid development in science and technology has paved its way for sophistication by automation. People now a days‚ are inclined towards devices that are sophisticated‚ simpler to use and secure. In this project entitled “Home Appliances Control using Different Controlling Modes “‚ a prototype is developed which shows how the best utilization of technology can be made in order to secure a home not only from threat but also by ensuring all the safety measures. The

Remote Control For Home Appliances This is a simple remote control circuit based on infrared sensor IC TSOP1738. TSOP1738 contains photo detector and pre-amplifier both in one package. It is a three terminal device. Pin 1 is for ground‚ Pin 2 is for power supply and pin 3 is used as output. Pin diagram of TSOP1738 is shown below. Take care while connecting the pins of TSOP1738. Wrong lead connection of TSOP1738 may lead to sensor damage. CD4017 is a CMOS counter/ divider IC. It takes clock signal

but using your phone as a universal remote is no longer a tech dream. TVs‚ DVD players‚ cable boxes and stereos use an infrared (IR) signal to know when to do things like change the channel or play the DVD. To convert your phone into a universal remote you’ll need to purchase a device called an IR blaster that takes the commands you give on your phone and converts them into infrared signals. There are different devices that can do this‚ from pear-shaped orbs you sit on your table to covers that fit

travels at different waves and spans in a very broad spectrum. This wide spectrum of wavelengths and photon energy is called the electromagnetic spectrum. There are 7 different types of waves in an electromagnetic spectrum; radio waves‚ microwaves‚ infrared waves‚ visible light‚ ultraviolet waves‚ x-rays and gamma rays. Each of these categories contains different type of waves‚ which varies in wavelength and photon energy‚ which is the units in which electromagnetic radiation come in. Figure 1. An

Till late 1990s infrared spectrum is used for the communication. But in the early 2000s‚ researches started using visible light from LEDs as the medium for communication. Initially they were able to achieve network speed about 100Kbps. With continuous developments‚ VLC systems

The gases have this effect because as incoming solar radiation strikes the surface‚ the surface gives off infrared radiation. The effect is comparable to the way in which a greenhouse traps heat and that is how we got the name greenhouse

This oil was identified as eugenol by comparison of its infrared spectrum with an authentic sample. POST LAB 2.) The active component is Eugenol. It is a phenylpropene‚ an allyl chain-substituted guaiacol. Eugenol is a member of the phenylpropanoids class of chemical compounds. It is slightly soluble in water
