Clip-On Monitor for Detecting Clogged Air-Filters

A monitoring clip to be secured to the edge of a filter cartridge includes a channel connecting both sides of the filter through which air will flow in response to the filter becoming clogged. Air flow within the channel will eventually be strong enough to pivotally move a flow vane. Controlling cir...

Summary:A monitoring clip to be secured to the edge of a filter cartridge includes a channel connecting both sides of the filter through which air will flow in response to the filter becoming clogged. Air flow within the channel will eventually be strong enough to pivotally move a flow vane. Controlling circuitry is used to detect the angular movement of the flow vane. When the flow vane moves to a "triggering" position, it is determined that the filter is clogged and requires replacement. Controlling circuitry will sound and illuminate a local alarm, and send a signal by Bluetooth or WiFi, to a smartphone. Although a clip format is preferred, the measuring and controlling circuitry of the monitoring clip can be also built into new filters.
