With single chip microcomputer and photosensitive resistance to achieve light intensity test, there is no voltage to light intensity conversion formula. I hope you can help me
The corresponding relation is obtained according to the light intensity resistance diagram, that is to say, the general photosensitive resistor can not be precisely divided, but the imported Cds photosensitive resistors are all equipped with chip data
Microcontroller computation ability is poor, for a variety of data change constantly, the look-up table method is a good method.
A photosensitive resistor to detect light intensity is generally not too accurate, generally uses the special chip to measure the illuminance, if does not require accurate measurement, a photosensitive resistor in general (nonlinear) can do, but need to find the type of photosensitive resistance
