hi..masters

nbasa ko po iyon mga forum tungkol sa ganito din topic..pwede po bang makahingi ng info dun sa kagawa na ng automatic ventian blind?

if you can give this same proposal but with lighting system much better,, we are still thinking pa po kasi kung isasama namin un sa illumination ng ilaw mukha po kasing complicated iyong magiging circuit nun..

tnx po..

bale 'yung sensor niyo ipapasok niyo sa loob ng hemispherical na diffuser to approximate 3D surfaces. dapat talaga 2 sensor or kahit 1 sensor sa loob, depende kasi sa angle nung rays ng araw, posibleng hindi masyadong makapasok 'yung liwanag sa blinds. may nakita ako dating research, LCD ang gamit instead na blinds para hindi masyadong malalaki 'yung obstructions.

parang ganito nga pala 'yung hemisphere diffuser:

incident light meter ang tawag diyan, tapos approximation ng integrating sphere 'yung hemisphere.

un incident light meter po ano po iyon magiging role nun sa project namin ndi po kasi ako pamilyar dun?

'yun lang ang dapat na comfiguration nung light sensor. siya 'yung magmeasure ng amount of light sa room or surface.
