I found limited documentation on the usage of a color sensor I recently purchased, so here is my attempt to make it more simple.

Ultra low-cost flow-through photometer for on-line measurements of bacterial density.

Just before creating my next tutorial, which will be using a PIR sensor, I thought I might create a separate tutorial for PIR Sensor.
