Monitor Your HVAC Air Flow - DPS Tele

What you need is the D-Wire Airflow sensor from DPS Telecom. When placed in front of a vent, this sensor measures the rate at which air is being pushed out of your HVAC unit. A decrease in this rate indicates that your filters need to be replaced. It can also alert you to any other flow problem with your HVAC unit before your network goes down.
