Due to an exceptional geographical location, Bangladesh can produce significant amount of solar energy, which is 1840-1575 kWh/m^2 annually. Because of that solar home system (SHS) is gaining enormous popularity in our country in social as well as business sector in our country. Since verities SHS components manufacturers, overall quality of LED lamps fluctuates from organization to organization, and as a result an increment in unsteady quality with the number of SHS installation occurs, which eventually causes system ineffectiveness. There are two existing lumen testing procedures - integrated sphere and goniophotometer method are quite costly in our country’s perspective. So we have to come up with handmade cylindrical box with different dimension and sizes in CARC lab of BRAC University. Researches already included the testing results and also have established equations based on the measurement of total lumen of light sources. In our thesis we will make automatic luminous measuring embedded box based on these equations using a micro-controller, which will show the output of the system on the screen of the embedded box.
