Questions with Optical Sensors - Photo Detectors - CdS Cells

  • Ask: What acts as detector in optical sensor?

    Answer: Combinations of light-emitting diodes (LEDs) and photodiodes are commonly used together in many optical sensor systems. Infrared sensors are commonly used for sensing of objects and detection of distances. An infrared sensor emits a pulse of infrared light from an emitter.

  • Ask: How do optical detectors work?

    Answer: Optical detectors convert incoming optical energy into electrical signals. ... Photon detectors produce one electron for each incoming photon of optical energy. The electron is then detected by the electronic circuitry. Thermal detectors convert the optical energy to heat energy, which then generates an electrical signal.

  • Ask: What is an optical detector?

    Answer: An optical detector is a transducer that converts an optical signal into an electrical signal. It does this by generating an electrical current proportional to the intensity of incident optical radiation.


  • Ask: What are photo detectors how they are used in optical Fibre?

    Answer: An optical detector is a device that converts light signals into electrical signals, which can then be amplified and processed. The photodetector is as essential an element of any fiber optic system as the optical fiber or the light source. Photodetectors can dictate the performance of a fiber optic communication link.

  • Ask: What does a photocell measure?

    Answer: How do light sensors work? A CdS cell is a large area photo resistor, made by depositing doped cadmium sulfide on a ceramic substrate. The CdS cell resistance changes in proportion to the amount of visible light; this allows more or less voltage/current to appear at the input of an electronic switching circuit.

  • Ask: How does a photocell sensor work?

    Answer: Photocells are sensors that allow you to detect light. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they often appear in toys, gadgets and appliances.


  • Ask: What are two devices that use a photocell resistor?

    Answer: Photocell. A photocell is a resistor that changes resistance depending on the amount of light incident on it. A photocell operates on semiconductor photoconductivity: the energy of photons hitting the semiconductor frees electrons to flow, decreasing the resistance. ... (Right) A simple light-level-detection circuit.

  • Ask: What is meant by LDR Sensor?

    Answer: Photocells may be used in the place of variable resistors and photovoltaic cells. Some circuit applications include light meters and light controlled relays.
