4. O2O Cerlic Blue light excites luminescent material
Red LED provides reference signal
The time for red light to be emitted off of luminophor is measured
Phase of both signals are compared
The measurement correlates to O2 concentration, increased amounts of O2 in the liquid decreases the time it takes for the red light to be emitted.
