Sesitive Round Diameter 5mm Photocell Cds Photoresistor Light Sensor GM55 Series For Sensor Application
Sesitive Round Diameter 5mm Photocell Cds Photoresistor Light Sensor GM55 Series For Sensor Application
Description
Ao littel photoresistor Light Sensor or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity. A photoresistor Light Sensor can be applied in light-sensitive detector circuits, and light- and dark-activated switching circuits. It's also called light-dependent resistor (LDR).

Photocells Light Sensor are sensors that allow you to detect light. They are small, inexpensive, low-power,easy to use and don't wear out. For that reason they often appear in toys, gadgets and appliances. They are often referred to as CdS cells (they are made of Cadmium-Sulfide), lightdependent resistors (LDR), and photoresistors.

Max. External Voltage: The max. voltage can be consistently imposed in the components in darkness.
Dark Resistance:The resistance which is get from closed the 10 lux light for 10 seconds. Max. Power:When the environment temperature is 25℃ using the biggest power Light Resistance:The resistance which is get after 400-600lux light for 2 hours, test with the standard light (CCT:2854K) 10 lux get the value.
Γ Value: The ratio gets from the standard resistance in 10 lux illuminance and 100lux illuminance’s rate.
Lg (R10/R100)
γ= =Lg(R10/R100)
