uxcell 10pcs Photoresistor LDR 4mm Light-Dependent Resistor Sensor GL4516
Feature：Photo resistors, also known as light dependent resistors (LDR), are light sensitive devices most often used to indicate the presence or absence of light, or to measure the light intensity.In the dark, their resistance is very high, sometimes up but when the LDR sensor is exposed to light, the resistance drops dramatically, even down to a few ohms, depending on the light intensity.LDR has a sensitivity that varies with the wavelength of the light applied and is nonlinear device. They are used in many applications but are sometimes made obsolete by other devices such as photodiodes.Please check the right type to meet your needs.Specification：Type: GL4516 Max voltage (VDC) :150Max power dissipation (mW): 50Ambient Temperature (C): -30~+70Peak wavelength (nm): 540Light resistance (10lx)(KΩ): 5-10Dark resistance(MΩ): 0.6Gamma Value (at 10 ~ 100 lx): 0.5Rise Response Time(ms): 30Fall Response Time(ms): 30Illuminance resistance characteristic: 2Body Size: 4 x 3.5 x 1.5mm (LWH)Wire size: 32mmPackage Content:10 x Photoresistors
Product Features
- Photo resistors, also known as light dependent resistors (LDR), are light sensitive devices most often used to indicate the presence or absence of light, or to measure the light intensity.
- In the dark, their resistance is very high, sometimes up to 1M, but when the LDR sensor is exposed to light, the resistance drops dramatically, even down to a few ohms, depending on the light intensity.
- LDR has a sensitivity that varies with the wavelength of the light applied and is nonlinear device.
- They are used in many applications but are sometimes made obsolete by other devices such as photodiodes.
- Please check the right type to meet your needs.
