#252: Photosensitive Sensor Module (Light Detector)

R14.78

Main parameters and characteristics

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 & 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 - 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 -Power Rating. Refers to the rated power for a certain line photoresistor allowed power consumed, when the temperature rise

High, its power consumption is reduced.
