Why using 555 timer in ir transmitter?
The 555 is a timer and oscillator chip capable of sourcing and sinking 200 milliamperes, and is useful for pulsing an infrared LED to power an infrared transmitter. It can be pulse width modulated or otherwise controlled via the various control pins. See: http://talkingelectronics.com/FreeProjects/555/555-P3.html in most cases the IR detector used is TSOP sensors which works only on a specified frequency of 38KHz. So by using 555 timer, we can design the circuit very easly to work @ 38KHz. dats why in 555 is used in many IR txns.
What is an ir detector?
In IR (InfraRed) detector is a circuit that receives an infrared input, either in an alarm or as a heat sensing device. In an alarm circuit, using an infrared beam rather than a laser has both advantages and disadvantages. Passive heat sensors rely on a general increase in temperature to identify a likely source, e.g. an animal, person, or vehicle engine.
How do you measure electrical insulation resistance value?
By Megger testing (meggering) of the motor any one can measure the IR of the motor. MEGGER is a device used to measure IR. Analog Megger device may generate 500 volts..it gives coil to coil or coil to body IR value...it should not be less than 2 Mega ohm, generally it should be or kept more than 5 mega ohm...thanks ...DEEPAK RAJPUT
Transformer Output power less than input power?
A: Absolutely a power transfer will have an internal loss of IR . for a power transformer the loss can be as much of 20% or more if other magnetics are involved like iron screw holding the lamination together. Usually brass is used to reduce that loss.
Why you can see the ir led through camera?
Most digital camera sensors are sensitive to a small range of IR, as well as visible light.
What is IR camera?
IR stands for infrared - the energy just below red light. Some of the digital camera sensors on satellites are sensitive to IR, and most consumer digital cameras are sensitive to IR to some extent, but have built-in filters to block it. These can be converted to IR by replacing the filter with a clear piece of glass. In the film era, there were special IR-sensitive films, that had to be handled very carefully.
What type of sensors do reversing cars use?

How does blocking IR light affect the performance of infrared sensors?
Blocking infrared (IR) light can significantly impact the performance of infrared sensors by reducing their ability to detect and measure infrared radiation. IR light is essential for these sensors to function properly, as it is the signal they use to detect and analyze heat signatures. Blocking IR light can result in decreased sensitivity and accuracy of the sensor, leading to potential errors or limitations in its performance.
What radiation is used for digital camera?
Infrared radiation (IR)
What are some applications of IR sensors?
Some applications of IR sensors are water and steel analysis, underground solution, temperature sensor, space operations, rail safety, planet health, petroleum exploration, alcohol testing, and flame detection.
What is the incremental concept of managerial economics?
Incremental analysis includes two concepts Incremental cost Incremental revenue IC is the additional cost incurred for additional output. In other words changes in cost due to changes in level of output. Whereas IR is the additional revenue from additional output or the changes in revenue due to changes in output. For every business decisions there is IR and IC. In order to determine whether the decision is sound or not we should compare the IC and IR of every decision. If the IR exceeds the IC, or IR is equal to IC the decision can be assumed as a sound decision.
