Detecting Light Density Over Raspberry Pi Camera Module
This program is designed to measure approximate value of inner light of a experimental room and give result as LUX value. The main work priciple is described below:
> Firstly recorded some measurements by a LUXMETER on a different light values.
> Next regression test applied on these Lux values and software results of the same light densities.
> The result of this analysis gave us X-constant and tolerence for the formula.
> With help of this formula the software output is about 5-10% tolerenced on 0 - 900 LUX.
Regression Result of Inner Lights ON Status
X Constant = 81.3161669250621
Tolerence Constant = 0.194858452777609
Regression Result of Inner Lights OFF Status
X Constant = 62.7637685159081
Tolerence Constant = 0.503275917659405
Before use need to calibrate for the new environment.
Dependencies of the project are below:
