What is an What is a Light Sensor?

A light sensor is an electronic device used to detect light. There are several types of light sensors. A photocell or photo resistor is a small sensor which changes its resistance when light shines on it. A CCD (charged coupled device) transports electrically charged signals and can be found in digital cameras and night-vision devices. Photomultipliers detect light and multiply it.

Types of Light Sensors

There are several different kinds of light sensors. At Future Electronics we stock many of the most common types categorized by supply voltage, output type, photo current, operating temperature range, peak wavelength and packaging type. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for maximum supply voltage are 0.5 to 5 V, 1.5 to 6 V, 2.4 to 3.6 V and 3 to 5.5 V. Peak wavelength can be as high as 580 m, with the most common sizes being 560 nm and 580 nm.

Light Sensors from Future Electronics

Future Electronics has a complete chip selection of programmable light sensors from several manufacturers that can be used as a motion light sensor, ambient light sensor, outside light sensor, security light sensor, traffic light sensor, light sensor for outdoor lights, automatic light sensor or for programming any circuit that might require a light sensor. Simply choose from the light sensor technical attributes below and your search results will quickly be narrowed in order to match your specific light sensor application needs.

If you have a preferred brand, we deal with AMS, Melexis, Panasonic Electric Works, ROHM Semiconductor and Vishay as manufacturers. You can easily refine your light sensor product search results by clicking your preferred light sensor brand below from our list of manufacturers.

Applications for Light Sensors:

Devices that include light sensors have several uses in scientific applications and in everyday consumer products. A light sensor may be part of a safety or security device like a garage door opener or a burglary alarm. These devices often work by shining a beam of light from one sensor to another. If this light is interrupted, the garage door won't close or the alarm will sound. Several modern electronics, including TV’s, computers and wireless phones use ambient light sensors in order to automatically control the brightness of a screen in situations where light intensity is high or low. These light sensors can detect the amount of light in a room and raise or lower the brightness to a more comfortable level. Light sensors can also be used in order to automatically turn on lights outside or inside a business or a home at night. Also, barcode scanners work using light sensor technology.

Choosing the Right Light Sensor:

When you are looking for the right light sensors, you can filter the results by various attributes with the FutureElectronics.com parametric search: by Output Type (Analog/Digital, Analog, Digital, Linear or Open Drain), Photo Current (2.4 µA, 50 µA, 60 µA, …) and Peak Wavelength ( from 520 nm to 580 m) to name a few. You will be able to find the right ambient light sensor, outside light sensor, motion light sensor, security light sensor, automatic light sensor, traffic light sensor, light sensor for outdoor lights or for programming any circuit requiring a light sensor.

Light Sensors in Production Ready Packaging or R&D Quantities

If the quantity of light sensors required is less than a full reel, we offer to customers many of our light sensor products in tube, tray or individual quantities that will help you avoid unneeded surplus.

In addition, Future Electronics offers its clients a unique bonded inventory program designed to eliminate potential problems that could arise from an unpredictable supply of products containing raw metals and products with long or erratic lead times. Talk with your nearest Future Electronics branch and find out more on how you and your company can avoid possible shortages.
