In the broadest definition, a sensor is an object whose purpose is to detect events or changes in its environment, and then provide a corresponding output. A sensor is a type of transducer; sensors may provide various types of output, but typically use electrical or optical signals. For example, a thermocouple generates a known voltage (the output) in response to its temperature (the environment). A mercury-in-glass thermometer, similarly, converts measured temperature into expansion and contraction of a liquid, which can be read on a calibrated glass tube.
Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base, besides innumerable applications of which most people are never aware. With advances in micro machinery and easy-to-use micro controller platforms, the uses of sensors have expanded beyond the most traditional fields of temperature, pressure or flow measurement, for example into MARG sensors. Moreover, analog sensors such as potentiometers and force-sensing resistors are still widely used. Applications include manufacturing and machinery, airplanes and aerospace, cars, medicine, and robotics.it is also included in our day-to-day life.
A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument.

At the 2008 CMA Music Fest, Young offered fans the opportunity to make personal recordings of dedications to special people in their lives. These fans received e-mails containing the song and the dedications.
Young told The Boot that he wanted to re-release it because it was popular with his fans. It was accompanied by a digital extended play of the same title, comprising that song and three cover songs, "to share with fans some of the musical voices that helped make me the man I am today."
Voices is a 1995 album by Greek electronic composer and artist Vangelis.
Its music was used in the soundtrack for the 1998 documentary Deep Sea, Deep Secrets co-produced by The Learning Channel and Discovery Channel, together with music from Vangelis next album, Oceanic.
The track "Ask the Mountains" was also used as the music for the TV commercial for the Hotpoint/Ariston Aqualtis washing machine. Caroline Lavelle, who has worked and played with people like Peter Gabriel, Loreena McKennitt and Afro Celt Sound System as well as David Gilmour, sings and plays cello on the song "Come to me". Paul Young and Stina Nordenstam also collaborate on that album.
Voices is a 1973 British horror film directed by Kevin Billington and starring David Hemmings, Gayle Hunnicutt and Lynn Farleigh.
After her young son accidentally drowns, a woman has a breakdown and is finally placed in a mental hospital. After her release, her husband takes her for a weekend at a secluded country mansion, hoping to help her recover.

Africa is an epic poem in Latin hexameters by the 14th century Italian poet Petrarch (Francesco Petrarca). It tells the story of the Second Punic War, in which the Carthaginian general Hannibal invaded Italy, but Roman forces were eventually victorious after an invasion of north Africa led by Publius Cornelius Scipio Africanus, the epic poem's hero.
Africa and De viris illustribus were partially inspired by Petrarch's visit to Rome in 1337. According to Bergin and Wilson (p. ix). It seems very likely that the inspirational vision of the Eternal City must have been the immediate spur to the design of the Africa and probably De viris illustribus as well. After returning from his grand tour, the first sections of Africa were written in the valley of Vaucluse. Petrarch recalls
The fact that he abandoned it early on is not entirely correct since it was far along when he received two invitations (from Rome and from Paris) in September 1340 each asking him to accept the crown as poet laureate. A preliminary form of the poem was completed in time for the laurel coronation April 8, 1341 (Easter Sunday).
