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.
