sensor field
1Field-effect transistor — FET redirects here. For other uses, see FET (disambiguation). High power N channel field effect transistor The field effect transistor (FET) is a transistor that relies on an electric field to control the shape and hence the conductivity of a… …
2Field of view (image processing) — The field of view of an imaging sensor or imaging system is defined as the maximum vertical and horizontal angular extent viewed by the sensor or system. Optical tests for measuring the FOV are versatile tests capable of measuring the FOV of UV,… …
3Sensor node — The typical architecture of the sensor node. A sensor node, also known as a mote (chiefly in North America), is a node in a wireless sensor network that is capable of performing some processing, gathering sensory information and communicating… …
4Field of view — The field of view (also field of vision) is the angular extent of the observable world that is seen at any given moment.Different animals have different fields of view, depending on the placement of the eyes. Humans have an almost 180 degree… …
5Planar Hall sensor — The planar Hall sensor [http://www.mic.dtu.dk/upload/institutter/mic/forskning/magnetic systems/reports/phd louiseejsing.pdf] is based on the planar Hall effect of ferromagnetic materials. [http://scitation.aip.org/getpdf/servlet/GetPDFServlet?fil… …
6Passive infrared sensor — A Passive InfraRed sensor (PIR sensor) is an electronic device that measures infrared (IR) light radiating from objects in its field of view. PIR sensors are often used in the construction of PIR based motion detectors (see below). Apparent… …
7Wheel speed sensor — [ head unit.] Wheel speed sensors or vehicle speed sensors (VSS) are sender devices used for reading the speed of the vehicle s wheel rotation. It usually consists of a toothed ring and pickup. Special purpose speed sensors Rotary speed sensors… …
8Fiber optic sensor — A fiber optic sensor is a sensor that uses optical fiber either as the sensing element ( intrinsic sensors ), or as a means of relaying signals from a remote sensor to the electronics that process the signals ( extrinsic sensors ). Fibers have… …
9Depth of field — The area within the depth of field appears sharp, while the areas in front of and beyond the depth of field appear blurry …
10Throttle position sensor — A throttle position sensor (TPS) is a sensor used to monitor the position of the throttle in an internal combustion engine. The sensor is usually located on the butterfly spindle so that it can directly monitor the position of the throttle valve… …
