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.
