10PCS ARDUINO AVR PIC Photosensitive Resistance Module new
Description : 1>. According to the spectral characteristics of the photoresistor has three photoresistor: Ultraviolet photosensitive resistance, infrared light-sensitive resistors,Visible photosensitive resistance. 2>. The main parameters are as follows: A>. Dark current, dark resistance: photosensitive resistance at a certain applied voltage, when the light is not irradiated when the flowing Current is called dark current. Applied voltage and dark current ratio as the dark resistance. B>. Sensitivity: Sensitivity is irradiated by light sensitive resistor, the resistance value (dark resistance) when irradiated with light Resistance value (light resistance) the relative change in values. C>. Volt-ampere characteristic curve.Voltage characteristic curves are used to describe the resi.
