  • Light Sensors

    Light sensors often use an infrared LED as a light source. Infrared LEDs have a greater intensity than LEDs that emit visible light. And when infrared photodiodes are used the sensors are relatively insensitive to ambient light. Photoelectric light sources are often modulated at a given frequency

  • ROHM's Ambient Light Sensor Applications in Portable Electronics (.pdf)

    in portable products. As a result, the use of an ambient light sensor (ALS) to optimize the operation of the backlight LEDs under a variety of environmental lighting situations is increasing while, at the same time, the preferred technology choices available to designers for sensing have shifted towards

  • Controlling Light

    Operational supplies are frequently used to regulate the intensity of heavy-duty light sources such as xenon or arc lamps. The uniform illumination of a monochronometer is a typical objective. Light sensors typically provide the regulating feedback. These sensors include photomultiplier tubes

  • Alternating Current (AC) powered light sources have variations in light output.

    Alternating Current (AC) powered light sources have variations in light output. This variation or flicker may affect a light sensor's output, which creates unwanted variations in light measurements unless appropriate techniques are used to filter out the flicker.

    Solar energy is rapidly advancing as an important means ofrenewable energy resource. More energy is produced by trackingthe solar panel to remain aligned to the sun at a right angle to therays of light. This paper describes in detail the design andconstruction of a prototype for solar tracking syste...

    Michael, I found the Motorola design reference manual on Passive Infrared Unit it's a PDF file. Motorola Design Manual I hopes this helps you. As several people have already said there PIR, ultrasound, radar, and laser ranging, also there vision systems. The PIR detects mot...

  • Re: Truck Loading Position and Speed Sensor

    Having as given your schematic diagram I would suggest you to think throughly to secure abslolutely foolproof level of safety for the project. As truck has to move slowly under uploading I think simple mechanicaly driven switches (as Envoroman suggested) look as quite good and reliable decision. At...

  • Re: logic -control narrative

    Logic is a command given in the control circuit. Depending on how the program is written it will create an output to turn something on or off depending on your inputs. Think of a fire alarm. All inputs are normal and as programmed until a fire starts and one of your sensors gets too hot. It imm...

  • Re: when can I called a cable to be a power cable

    I agree to the comments provided by others, but here is some additional information: Cables are identified by three categories in this context: Power cable, Control cable and Instrument cable. These categories are based on what the cables are carrying. Power cable: These are the cables who...

  • Re: Jeep Grand Cherokee, 1998, Automatic Shutdown Device

    Thanks for the info. I had already replaced both of these sensors and the relay. Now the problem is getting worse. I don't know if this is related, but now the gage cluster turns off while driving. All the dials turn off. No tac, no speed, no oil, no amp, no gas, no oil but have dash lights and turn...

Ambient Light Sensor

PR5001 is a dual-element Si photodiode molded into a very small plastic leadless optical package.     The photo diodes offer a good symmetry,low dark current and high sensitivity. The spectral sensitivity starts at 400nm and ranges to the near infrared at 1050nm. An ambient light sensor for automotive applications has been realised in the same package. A monolithically integrated amplifier and voltageto-current converter allows to use a two-wire interface.
