PN:610116
The Broadsensor optical DO sensor(diameter 16mm) is coated
with a luminescent material. Blue Light from an LED strikes the
luminescent chemical on the sensor. The luminescent chemical
instantly becomes excited and then as the excited chemical relaxes,
it emit red light. The red light is detected by a photo diode. The
time it takes for the chemical to return to a relaxed state is
measured by referring an independent red led light. Oxygen has a
dampening effect on this reaction. The oxygen concentration is
proportional to the time it takes for the luminescent material to
return to a relaxed state.
