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.
Jeka Wynzorr, codenamed Sensor, is a fictional character, a superheroine in the future of the DC Comics universe, and a member of the Legion of Super-Heroes.
She is a snake-like alien, who was later altered by "Hypertaxis energy" and Ra's al Ghul into a semi-humanoid shape, retaining her serpent's tail but gaining a humanoid upper body.
Jeka Wynzorr was the princess of the planet Orando, a world populated by a ruling class of large, sentient, snakes and an underclass of (similarly sentient) small, raccoon-like mammals. However, she renounced this heritage to travel the galaxy, using her illusion-casting powers to disguise herself as a humanoid to avoid attention. It is not explained how her race, which lack manual manipulators, constructed an advanced civilization; however, it is implied that it may have been via the enslavement of the raccoons. Upon joining the Legion, she immediately donned a set of cybernetic arms, which she was thereafter rarely seen without.
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.

Michael Leunig (born 2 June 1945), typically referred to as Leunig (his signature on his cartoons), is an Australian cartoonist, poet and cultural commentator. His best known works include The Adventures of Vasco Pyjama and the Curly Flats series. He was declared an Australian Living Treasure by the National Trust of Australia in 1999.
Leunig, a fifth generation Australian, was born in East Melbourne, grew up in the Melbourne suburb of Footscray where he went to Footscray North Primary School. When time came for him to go to high school, he first had to attend classes held at the nearby Royal Melbourne Showgrounds as his school, Maribyrnong High School, hadn't been finished yet. He failed his final year examinations, twice.
After working as a labourer in an abattoir, Leunig enrolled at the Swinburne Film and Television School, where he was at first interested in making documentaries. He was conscripted in the Vietnam War call-up, but he registered as a conscientious objector; in the event, he was rejected on health grounds when it was revealed that he was deaf in one ear.
