5528 5MM 10K-20K Photoresistor Light-Dependent Resistor Sensor GL5528

This photoresistor changes its resistance in the presence of light.

Condition: NEW, 100% Good Quality
Maximum Voltage: 150 Volt DC
The Max power consumption(mw):100
Operating Temperature: -30 ~ +70 deg C
Spectral Peak: 540nm
Light Resistance （10Lux）（KΩ）:10-20
Dark Resistance: （MΩ）:1
100λ10：0.6

It can be used to measure light/dark or the relative brightness of light sources. It is extremely easy to interface to the analog input pins on an Arduino, Netduino or other microcontroller (PIC, AVR, etc.), as well as an easy device to use in analog circuits.


Photoresistors are also known as "CDS Cells" or "LDRs" (Light Dependent Resistors).

This is a must-have part for any hobbyist or young electronics enthusiast. Its great for classroom electronics demonstrations and science fairs. This is the sensor at the heart of dusk-to-dawn sensors, automatic headlights, etc.
