Light dependend resistor is an electronic component capable of detecting ligh
What is resistance?
The resistance measures the oposition of an electric current throught a conductor. The units are Ohms (Ω)
Electrical resistance, the measure of the degree to which a conductor opposes an electric current through that conductor (WIKIPEDIA DEFINITION).
What is ilumination?
Ilumination is the degree or intensity of light. The units to measure light are lux.
|Illuminance||Surfaces illuminated by:|
|0.0001 lux||Moonless, overcast night sky (starlight)|
|0.002 lux||Moonless clear night sky with airglow|
|0.27–1.0 lux||Full moon on a clear night|
|50 lux||Family living room lights(Australia 1998)|
|100 lux||Very dark overcast day|
|320–500 lux||Office lighting|
|400 lux||Sunrise or sunset on a clear day.|
|1000 lux||Overcast day; typical TV studio lighting|
|10000–25000 lux||Full daylight (not direct sun)|
|32000–100000 lux||Direct sunlight|
The numbers are not distributed linearly. It means that a number 0.0001 lux compared to 100000 lux are difficult to represent.
We need to represent using scientific numbers:
10^-4 = 0,0001
10^2 = 100
10^5 = 100000
