KY-018 3Pin Optical Sensitive Resistance Light Detection Photosensitive Sensor Module

Description 1 According to the spectral characteristics of three photoresistor UV light sensitive resistors infrared light sensitive resistors visible photoresistor 2 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 3 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 4 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 5 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 6 Rated powe Refers to the rated power for a certain line photoresistor allowed power consumed when the temperature rise high its power consumption is reduced Package included 1 x KY 018 Photosensitive Sensor Module
