Method and system for smart air filter monitoring
First Claim
1. A smart air filter monitoring system for a cabinet for electronic devices comprising:
- a filter support frame adapted to be mounted to or in a cabinet;
an air filter removably mounted to the filter support frame, the air filter having filter media positioned in an air flow within the cabinet so that at least a portion of the air flow in the cabinet passes through the filter media, the filter media having a first side and a second side, the air passing from the first side through the filter media to the second side;
a light emitting device located adjacent to the air filter and positioned to emit light toward the air filter;
at least two light sensors mounted near the air filter, each light sensor directed to the air filter to receive light emitted from the light emitting device after the emitted light has passed through the air filter, the light sensors adapted to generate electrical signals from the emitted light striking the light sensor; and
a controller electrically connected to the sensors and adapted to receive the signals from the light sensors, the controller configured to provide a signal for indicating that the filter needs to be serviced when the controller calculates that the electrical signals indicate that the air filter needs to be serviced.

Abstract
In one aspect of the invention a smart air filter monitoring system for a cabinet for electronic devices is provided that includes: an air filter positioned in an air flow so that substantially all the air flows through the filter, the air flow being defined by the cabinet; a light emitting device on a first side of the air filter; at least two light sensors mounted near the air filter, each light sensor directed to the air filter to receive light emitted from the light emitting device after the emitted light has passed through the air filter, the light sensors adapted to generate electrical signals from the emitted light striking the light sensor; an electrical circuit, the electrical circuit generating a signal for indicating that the filter needs to be serviced when the electrical circuit determines that electrical signals received from a combination of the sensors indicates that the filter needs to be serviced.

26. A method for monitoring a smart air filter of a cabinet for electronic devices comprising:
-
emitting light by a light emitting device toward an air filter positioned in an air flow within a cabinet; generating electrical signals in response to light striking at least two light sensors located adjacent to the air filter, the light sensors directed to the air filter to receive light emitted from the light emitting device after the emitted light has passed through the air filter; in response to receiving the generated electrical signals, calculating whether the air filter needs to be serviced based on the generated electrical signals, and when the air filter needs to be serviced, providing a signal for indicating that the filter needs to be serviced. - View Dependent Claims (27)
