The main parameters are as follows:

Dark current, dark resistance – photosensitive resistance at a certain applied voltage, when the light is not irradiated while the flowing current is the dark current.

Sensitivity – irradiated by light sensitive resistor, the resistance value when irradiated with light resistance changes in relative values.

Volt-ampere characteristic curve – used to describe the resistance of the applied voltage and the photosensitive-photocurrent relationship.

Temperature coefficient – photoelectric effect photoresistor affected by temperature.

Rated power – allowed for certain lines in the power consumed.
