Estimation of nitrate in water samples using microcontroller

A simple and cost effective colorimetric spectrophotometer for determining nitrate levels in water samples has been developed.
The system consists of an ultra blue LED as the light source, sample holder, a photo diode as the detector and micro
controller for acquiring and processing the data.

Keywords: Beer-Lambert’s law, microcontroller, nitrate, photodiode, ultra blue LED
