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. For example, a mercury thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube.... is any device that enables position measurement. It can either be an absolute position sensor or a relative one (displacement sensor). Position sensors can be either linear or angular.

An inductive sensor is an electronics proximity sensor, which detects metallic objects without touching them.The sensor consists of an induction loop....
A string potentiometer is a transducer used to detect and measure linear position and velocity using a flexible cable and spring-loaded spool. Other common names include "string pot", "cable-extension transducer", "draw wire sensor", and "yo-yo sensor".... (aka String Pot)
The linear variable differential transducer is a type of electrical transformer used for measuring linear displacement. The transformer has three solenoidal coils placed end-to-end around a tube.... (LVDT)
A potentiometer is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider. If only two terminals are used , it acts as a variable resistor or Rheostat....
A Hall effect sensor is a transducer that varies its output voltage in response to changes in magnetic field. Hall sensors are used for proximity switching, positioning, speed detection, and current sensing applications....
A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic or electrostatic field, or a beam of electromagnetic radiation , and looks for changes in the electric field or return signal.... (optical)
A rotary encoder, also called a shaft encoder, is an electro-mechanical device used to convert the angle position of a shaft or axle to an analog or digital code, making it an angle transducer.... (angular)
A photodiode is a type of photodetector capable of converting light into either electric current or voltage, depending upon the mode of operation.... array
Array
In computer science, an array is a data structure consisting of a group of element s that are accessed by index . In most programming languages each element has the same data type and the array occupies a contiguous area of computer memory....

A linear encoder is a sensor, transducer or readhead paired with a scale that encodes position. The sensor reads the scale in order to convert the encoded position into an analog or digital signal, which can then be decoded into position by a digital readout ....
