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.

What does IR use to receive data?

An Infra Red detector !


What does IR use to transmit data using?

Infra Red light ! I'm guessing you also asked the question 'What does IR use to receive data' too. Basically there is an IR diode in the transmitter, and a detector in the receiver. The amount of IR emitted by the diode varies with voltage, so when the detector receives the pulse, it can 'de-code' what's being sent.


What components are needed to make a light sensor?

well when you talk in electronic subjet we said circuits you need ,but you normally buy a seurity ir detector and put (don´t know this in english contator is mall piece with metal like electric engines and 2 votages gates one is generated for ir detector and the other one is for you main circuit as alarm when the ir detector turn on that part of the contator the both circiuts turns on) both are normally close another is a laser alwais on mirror and circuit who detect when light is off that circuit I know needs diode sensor and chip with gates and true table


What is the difference between pir movement sensor and ir sensor?

Passive simply means that the unit does not emit IR light, but does detect it. All warm things emit some degree of IR. a PIR motion detector senses the difference between a warm body and the cold background. Active IR emits IR light to illuminate an area to be "seen" with it's CCD that is sensitive to IR. Most new Sony camcorders use active IR for "night vision". IR alone, with no modifier, simply refers to the spectrum of light known as Infra Red, which is slightly above human's vision range.


How does flame detector works?

A flame detector is a fire protection device, which detects the flame in the place where it is fixed and issues an alarm thereby alerting nearby people to the danger of fire. In most of the manufacturing companies, furnace flame detector is used in order to detect and prevent fire. Flame detector responds either to radiant energy visible to the human eye or outside the range of human vision. Most flame detectors work either by optical flame detector or flame ionization detector but some of them use combination of both detectors.Flame detector works at specific ranges, which uses optical sensors to record the incoming radiation at a particular wavelength. The energy radiated from the flame is electromagnetic radiation and it can be identified at various spectral ranges like UV, IR and VIS. Depending upon the sensor used there are number of flame detectors available they are infra red flame detectors, ultra violet flame detector, UV/IR, IR/IR and tripe IR spectral band detector. Flame detector has a cone of vision that defines the effective capability of sensing fire. It is inefficient for slow fires however it responds faster for rapidly developing fire like combustible gas and liquid. It is available in different shape and size.

How IR sensor works?

IR detector(InfraRed detector) A sensing device that picks up radiation in the infrared band. Used extensively for still and video night vision cameras, cooled IR detectors can sense the makeup of nebulae light years in the distance. The IR industry is maturing rapidly and is expected to make devices that detect a myriad of conditions, including irregularities in machinery, ice on aircraft wings and faults in circuit boards.Infrared detection works because most everything in our known world gives off heat, which emits radiation in the infrared band.Above retrieved from Answers.comViper1


Do all motion sensors have a transmitter and a receiver?

Some devices have the receiver and transmitter built into the same device. Some devices use only a detector and register changes in emitted IR "patterns" (for example) to infer motion.


What is the instrumental difference in IR and FTIR?

The main instrumental difference between IR (infrared spectroscopy) and FTIR (Fourier-transform infrared spectroscopy) is the way in which the spectra are collected. In IR, the instrument measures the absorption of infrared radiation directly, while in FTIR, the instrument measures the interference pattern created when an infrared beam passes through a sample and a reference. FTIR is generally more sensitive and provides better resolution compared to traditional IR spectroscopy.
