Control HVAC air pressure open original image

Hi I have an Motorola air pressure sensor.

I would like to allow it to regulate the air pressure in my house ducts and have it control my blower motor.



Has any one seen a schematic that could be used to interface a Triac to an air pressure sensor ?



The motorola sensors are kind of expensive, doe anyone know of a cheaper solution ? than this one



thanks
