Simple and tiny RGB photo absobance meter

Rough scketch of final project : tiny absorbance meter.

This is simple optical measurement system for laboratory. The chamber is holder for glass cell (10mmx10mmx45mm) that contains sample solution. The meter can measure "ABSOBANCE" that means the absorbing light properties calculated by Log(paased light / injected light). In this system, three wavelengthes were used for measurement, 450, 520 and 620nm in wavelength. The embeded micropocessor board controls LED and photosensor, calculated asobance and send result to PC via USB or wireless connection.
