KY-018 3pin Optical Sensitive Resistance Light Detection Photosensitive Sensor Module for arduino

  • Tech Specs

    • 1, according to the spectral characteristics of three photoresistor photoresistor: UV light-sensitive resistors, infrared light-sensitive resistors,
    • Visible photoresistor;
    • 2, the main parameters are as follows:
    • A, dark current, the dark resistance: photoresistor at a certain applied voltage, when no light irradiation, when flowing
    • Current is called dark current. Applied voltage and the dark current ratio is called dark resistance;
    • B, Sensitivity: Sensitivity refers to the resistance value of the photoresistor from light irradiation (dark resistance) when irradiated with light and the
    • Resistance (light resistance) of the relative change value.
    • C, voltage characteristic curve. Volt-ampere characteristic curve used to describe the relationship between the applied voltage and the photoresistor photocurrent, of
    • The photosensitive device, its photocurrent increases with the applied voltage.
    • D, the temperature coefficient. Photoelectric effect photoresistor influenced by temperature, partial photoresistor optoelectronic at low temperatures
    • Higher sensitivity, whereas the sensitivity at high temperatures are lower.
    • E, rated power. Refers to the rated power for a certain line photoresistor allowed power consumed, when the temperature rise
    • High, its power consumption is reduced.
