Detects the amount of direct light.

Electronics Tutorial about Light Sensor including Photocells, LDR, Photodiodes, Phototransistors, Photovoltaic Cells and Light Dependent Resistor.

The resistance of photo-resistor decreases when the intensity of light increases. A dual OpAmp chip LM3on board produces voltage corresponding to intensity of light(i.e. based on resistance value). Tired of remembering to turn off your outdoor lights? Let our light sensor bulbs take care of this for you.

Light sensor bulbs turn on at dusk and turn off at dawn automatically. A quick an easy solution – no messy complicated electrical installations. Compared to low cost CdS cells, this sensor is more precise, allowing for exact . Due to the high rejection ratio of infrared radiation, . Use this Bit to control your circuits with light. The amount of light shining on the sensor will change how your circuit behaves.

Recommended for College, High School, and Middle School Science. Requires an interface and software, sold separately. The Light Sensor approximates the human eye in spectral response. Use it for inverse square law experiments or for studying polarizers, . With exposure to daylight, this sensor will output 5V. There is an analog light sensor , part number ALS-PT1 in the top left part of the board.

This can be used to detect ambient light, with similar spectral response to the human eye. With industry- leading research and design tools, Arrow makes finding the right part easy. It works based on sensing the intensity of light falling on light sensor. This RobotGeek Light Sensor is an analog sensor that will allow you to measure light from your Arduino or other microcontroller.

The more light the sensor detects , the higher the your analog port will detect. Their ultra low light sensitivity, low power consumption, ideal spectral response, and easy to use simple output algorithm make them best-in-class. ROHM ambient light sensors feature optical characteristics close to the human eye, enabling automatic backlight adjustment in displays for lower power consumption and optimum visibility.

The LilyPad Light Sensor is an e-textile friendly version of the Ambient Light Sensor Breakout. SMT PIN Photodiode with Vlambda characteristic, very linear ambient light sensor.
