smhjn17 Posted November 29, 2015 Posted November 29, 2015 Is their an equation for an LDR that can convert the value of resistance obtained into the incident light intensity?
Endy0816 Posted November 29, 2015 Posted November 29, 2015 (edited) This link gives a rough equation down in the practice section. http://home.roboticlab.eu/en/examples/sensor/photoresistor You might be able to locate tech specs for your specific resistor instead though.

John Cuthber Posted November 29, 2015 Posted November 29, 2015 The relationship will be device dependent, wavelength dependent and, I think, temperature dependent too.
Klaynos Posted November 30, 2015 Posted November 30, 2015 The relationship will be device dependent, wavelength dependent and, I think, temperature dependent too. I'd agree with that.
smhjn17 Posted November 30, 2015 Author Posted November 30, 2015 So isnt their an equation that will include resistance and intensity in proportion and other factors of the ldr in a constant?
