Sensor

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.

Sensor (comics)

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.

Fictional character biography

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.
