The proposed system mainly consists of 3 modules‚ viz.‚ telephone interface circuit‚ transmitter and receiver. The transmitter module is in turn made up of a digital data processing block and a wireless (infrared) transmitter block and the receiver module is made up of a wireless (infrared) receiver block‚ digital data processing block and a decoding block. In the scheme‚ a telephone receiver acts as a remote terminal to provide input Dual-Tone Multi-Frequency (DTMF) signals to the

Infrared radiation light is simply electromagnetic radiation with longer wavelengths (The American Heritage Student Science Dictionary 177). Infrared is usually called Infrared light‚ though it’s not visible to the human eyes (The American Heritage Student Science Dictionary 177). Infrared light is detected by a robot (Finio). Visible

create a circuit with an 8051 microcontroller that sensed when an object passed through an infrared receiver’s receive path to automatically turn on lights and count how many times the receive path was blocked. Discussion To complete the project several smaller circuits were needed to be designed and constructed. The project needed a circuit to pulse an infrared LED at 38 kHz‚ a circuit to receive the infrared signal‚ a seven segment LED display circuit‚ an auto-lighting circuit‚ and a programming

determine it base on finding the melting point and observing the Infrared Spectroscopy. Since copper is a hard metal‚ it will most likely bond to an oxygen atom because they are both hard. In the second experiment‚ I also synthesized RuCl2~4DMSO to determine which DMSO atom; Sulfur or Oxygen‚ combines to Ruthenium (III) to be reduced to Ruthenium (II). I was able to determine it based on finding the melting point and observing the Infrared Spectroscopy. Since ruthenium is a soft metal‚ it will most

The Advantages of Engineering Planet Earth is getting a lot warmer due to the greenhouse effect which heats up the surface of our planet from the presence of gases in our atmosphere. These gases allow for invisible rays of energy called infrared radiation to be emitted. It is widely believed that this is happening likely because of human activity and the burning of fossil fuels. But there is also great skepticism that it may not be human created‚ but rather a dramatic increase in solar activity

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 approximate temperature would be 3767 degrees C ii) If we observe a stars spectrum and find that the peak power occurs at the border between blue

interesting ways to travel‚ and we don’t mean surfing! Many things we use every day involve waves. Lights and sounds are examples of everyday uses that travel by wave. On the spectrum of light there are waves listed which are X-Rays‚ UV-Rays‚ and Infrared. Some of these are harmful to life‚ and some of these are helpful to life‚ where mostly they all serve both of these purposes. Another type of wave‚ though not on the spectrum because it is not light‚ are sound waves. Weather the wave is a sound

devices via infrared signals and a few via radio signals. Earlier remote controls in the 1970s used ultrasonictones. The remote control code‚ and thus the required remote control device‚ is usually specific to a product line‚ but there are universal remotes‚ which emulate the remote control made for most major brand devices. The main technology used in home remote controls is infrared (IR) light. The signal between a remote control handset and the device it controls consists of pulses of infrared light

headlines regarding “extreme weather events” occurring around the world and here in America left a curiosity about the history and technology used to forecast the Earth’s weather. Around the world meteorologists use technology such as satellites‚ infrared‚ radio‚ and radar transmissions‚ to help determine the most accurate forecast possible. However‚ even with the most advanced technology available‚ no predication is 100% accurate. Captain Robert Fitzroy of Great Britain started a forecasting system
