KY-018 3Pin Optical Sensitive Resistance Light Detection Photosensitive
Sensor Module
·
Photo resistors are semiconductor photosensitive devices, in addition to
having high sensitivity, fast response, consistent with the spectral
characteristics and value of good features
·
Working voltage: 5V
·
Under a high temperature, and humidity in harsh environments, it also
can maintain a high degree of stability and reliability
·
With good performance and high-quality material
Description
·
According to the spectral characteristics of three photoresistor:
UV light-sensitive resistors, infrared light-sensitive resistors, visible photo
resistor
·
Dark current, the dark resistance: photo resistor 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
·
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.
·
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.
·
The temperature coefficient: Photoelectric effect photoresistor
influenced by temperature, partial photoresistor optoelectronic at low
temperatures higher sensitivity, whereas the sensitivity at high temperatures
is lower.
·
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.
