The invention provides a dust repellant and anti-reflective inorganic coating and the method for preparing the coating. The dust repellant and anti-reflective inorganic coating includes nano-porous silica (SiO) network of about 5 nm to about 35 nm and is characterized by cracks. The method of preparing the dust repellant and anti-reflective inorganic coating on a substrate includes mixing of aqueous SiOsolution with a solvent. The aqueous SiOsolution with the solvent is stirred to form a solution. The solution is coated on the substrate to form a film on the surface of the substrate. Thereafter, the film is annealed by heating the film to a temperature of about 500&#xb0; C. to about 700&#xb0; C. within a period of about 2 minutes to about 2 hours. Finally, the film is allowed to cool down.

The invention provides an illumination measuring module which includes a housing and a photo detector. The housing is molded with a plurality of surfaces. Each surface of the housing is affixed with respective side edges of the plurality of the surfaces to form a predetermined shape. Each surface includes an external surface and an inner surface. One surface of the plurality of surfaces is a glass surface. The glass surface transmits illumination collected from an external ambience of the housing to one or more inner surfaces corresponding to the plurality of surfaces. On an inner surface of the glass surface, a plane white sheet is positioned which homogenously scatters illumination collected from the external ambience into the one or more inner surfaces in the housing. The photo detector measures scattered illumination diffused from the one or more inner surfaces corresponding to the plurality of surfaces.
