Abstract
A clogged filter detector is provided. In some embodiments, the clogged filter detector may comprise a transmitter, a sensor, and a transmitter resistor array configured to modify the output strength of the transmitter. In some embodiments, the clogged filter detector may comprise a transmitter, a sensor, and a sensor resistor array to configured to adjust the strength of the signal output by the sensor. The clogged filter detector may also include one or more processor configured to adjust the strength of a beam output by the transmitter based on a saturation level.
Claims24
A clogged filter detector comprising:
- a transmitter configured to emit a beam of electromagnetic radiation;
- a sensor configured to receive the beam of electromagnetic radiation after the beam passes through a filter;
- and
- a transmitter resistor array comprising a plurality of resistors, and configured to adjust an output strength of the transmitter by selectively controlling one or more of the plurality of resistors.
