Sensors invites you to join the Findit-Fixit Forum, where you can get answers to your sensing questions—concerning technologies, products, methods, applications, and services--and also offer help to your fellow engineers.
A new approach to wireless sensor networking adds local intelligence to the nodes, creating pervasive computers and enabling sensor networks that can both acquire data and initiate action without human intervention.

  Sensors: Camera System: Glossary: Learn: Digital Photography Review
The new Foveon sensors are based on the same principle, and have three sensor layers that measure the primary colors, as shown in this diagram.
As shown in this diagram, a "color filter array" is positioned on top of the sensor to capture the red, green, and blue components of light falling onto it.
In CCD (Charge-Coupled Device) sensors, the pixel measurements are processed sequentially by circuitry surrounding the sensor, while in APS (Active Pixel Sensors) the pixel measurements are processed simultaneously by circuitry within the sensor pixels and on the sensor itself.

Sensors are any device that turns (technical term "transduces") some kind of analog environmental information (motion, temperature, proximity, etc.) into an electrical signal that can be interpreted by a microcontroller.
Sensors can be as simple as a switch (which is wired to produce 0 or 5 volts), or as complext as a GPS receiver that outputs the latitude and longitude of the current location.
When the sensor data equals zero, the graphic will be positioned at the top of the screen, when the data is 480, the graphic will be positioned at the bottom of the screen.

 Saffo: essays: Sensors: The Next Wave of Infotech Innovation
The impact of sensors will be as surprising in the decade ahead as that of microprocessors in the 1980s and lasers in the 1990s.
The way to make long-term sense of sensors and their place in the digital technology complex is to think explicitly in terms of first-, second-, and third-order impact, and beyond.
Thus, the long-term consequence of the coming sensor revolution may be the emergence of a newer analog computing industry in which digital technology plays a mere supporting role, or in some instances plays no role at all.

 IEEE Spectrum: Smart Sensors   (Site not responding. Last check: )
But sensors have a dirty little secret: it's all too easy for them be in perfect working order, reporting all is well when, in fact, your milk is turning into a frozen block, the reactor's safety system is impotent, and that factory has filled a warehouse with useless—and possibly dangerous—products.
The dirty little secret of sensors is calibration, the process by which data from a sensor are mapped to real-world conditions, and the new standard should help make miscalibration a thing of the past.
Analog sensors typically output a voltage that is proportional to the magnitude of whatever it is they've been designed to measure—be it temperature, pressure, or something more exotic.

 EasySense Range: SmartQ Sensors
SmartQ sensors are all equipped with built-in circuitry that enables the sensor to be automatically identified by both the Logger and the Sensing Science 3 software.
With SmartQ sensors, however, the calibration table is placed directly into the sensor which is clearly a superior design in terms of accuracy and flexibility.
However, some sensors, such as pH, will gradually lose their accuracy unless they are manually calibrated to a known standard.

 SEMINAR
A popular fiber optic sensor, the fotonic sensor is a displacement sensor containing two groups of fiber optics, one set connected to a light source and termed the transmitting fibers, and the other set connected to a photo detector (photodiode) and known as the receiving fibers.
A light source, usually a laser, projects a beam of light onto the surface to be measured; the light is then reflected through a lens, say to point "A." Because the location of "A," the light source, and the lens' properties are all known, it's possible to infer the position of the reflection surface.
As a result, almost all triangulation sensors use a laser as the light source, and most standard sensor designs today use a solid-state laser, similar to the type used in common laser pointers.

Wireless sensor devices, or "motes," package together a circuit board with networking and application software; interfaces to sensors that can detect changes in temperature, pressure, moisture, light, sound, or magnetism; and a wireless radio that can report on their findings--all powered by a pair of AA batteries.
So instead of every sensor transmitting its information to a remote base station, an electronic bucket brigade moves data mote by mote until it reaches a central computer where it can be stored and analyzed.
And BP envisions using wireless networks of sensors to monitor industrial plants and ships, remotely adjust lighting and heat in office buildings, test soil for pollutants, and detect whether chemicals are stored properly.
