  • 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

    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.

    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...

  • Alta Devices to Describe Why Solar isn't Just for Sunlight Anymore

    What: Alta Devices ( will describe how its AnyLight™ technology can power sensors for a variety of applications using indoor light. This is a result of Alta’s unique technology that not only holds a world-record for efficiency at 28.8%, but also captures substantial energy under extremely dim indoor lighting conditions. Where: Sensors Expo, Donald E. Stephens Convention Center, Rosemont, Il. When: June 24-26, 2014 in Rosemont, Il. Booth #927. Special presentation on using this technology for autonomous sensors, June 25, 2014 from 3:30-4:10 pm. Why: Big data starts with small sensors. By 2020, there will be over 25 billion devices connected via the internet. Since many of these will be unplugged from a fixed power source, providing power will be a fundamental concern. Alta Devices will discuss this issue and how its technology can provide power by converting energy from ambient light. This has the potential to address a critical need for sensors in home, building, and factory automation as well as the internet of things and wearable devices. About Alta Devices Alta Devices is (EM)POWERING THE UNPLUGGED WORLD™ by delivering the world’s most efficient, thin and flexible mobile power technology. By converting light of any kind into electricity, Alta Device’s AnyLight™ power technology extends the energy source of a system, and in many cases, completely cuts the traditional power cord. The solution can be completely integrated into the final system, and is ideal for use in unmanned systems, consumer electronics, sensors, automotive, remote exploration, or anywhere size, weight, and mobility matter. Alta Devices holds world records for energy conversion efficiency and is headquartered in Sunnyvale, CA. For more information, visit
