How a Charge Coupled Device (CCD) Image Sensor Works

+

· HOW A CHARGE COUPLED DEVICE (CCD) IMAGE SENSOR WORKS QUANTUM EFFICIENCY The percentage of photons that are detected is known as the Quantum Efficiency (QE) of a detector. The human eye has a QE of approximately 20%, photographic film has a QE of around 10%, and modern day CCDs achieve a QE of over 90%. Quantum …

Infrared Remote Controls: Inside How Remote Controls ...

+

· The dominant remotecontrol technology in hometheater applications is infrared (IR). Infrared light is also known as plainold "heat." The basic premise at work in an IR remote control is the use of light to carry signals between a remote control and the device it''s directing. Infrared light is in the invisible portion of the electromagnetic spectrum.

How do remote thermostats work?

+

· Click to see full answer. Beside this, how do thermostats with remote sensors work? A remote sensor is a device designed to enable the thermostat to control room temperature based on the occupancy and temperature levels of the room. The normal wireless thermostat works by sensing the temperature of the surrounding areas and adjusting the heating or cooling system accordingly.

How does remote control of a TV work? Techulator

+

· Actually TV remote works on the principle of InfraRed waves. The press made by you is translated into IR wave to give the signal to the sensor placed in the TV. This process is carried through the a PCB which has the necessary components such as Chip, Diodes, Transistors, Resistors, Resonators and so on.

How Danfoss Thermostatic Radiator Valves Work.

+

The remote sensor is placed beneath the radiation or on a draftfree wall. Easy to use—just turn the dial: The desired control temperature is set by rotating the dial (sensor head) to the setting appropriate to the space—hallways, bedrooms, kitchens, living …

What is remote sensing and what is it used for?
