A Photodetector is a device that detects light and converts it into electrical signals, functioning as a light sensor or photosensitive element. It is used in various devices like TV remotes and automatic door systems, often utilizing infrared light.
Photoresistors are used in light meters, indoor thermometers, camera exposure meters, and for controlling street and car lights. They are sensitive to changes in electrical resistance based on light exposure.
Photodiodes are used in light intensity meters, CD players, smoke detectors, TV remote receivers, automatic faucets, solar cells, and image sensors.
Phototransistors, known for high sensitivity, are used in infrared remotes, cameras, optical communication, and automatic doors.
These convert light into heat, measuring changes in electromotive force, conductivity, and pyroelectric effects. Examples include thermopiles, bolometers, and pyroelectric elements.
Quantum-type elements measure changes in current, conductivity, and electromotive force due to carrier excitation. Examples include phototubes, photomultiplier tubes, photocells, photodiodes, phototransistors, and CCDs.
Allows non-contact detection by illuminating the target and receiving reflected or transmitted light.
Can detect various materials including metals, non-metals, liquids, and glass.
Offers high-speed response and precise detection without mechanical motion.
Can distinguish colors based on the difference in light wavelengths.
Measure reflected light from the target with combined emitter and receiver units.
Project light through the target to a receiver, measuring light obstruction. Suitable for long-distance stable detection.
