1. A mitigation system for monitoring pressure for a building having a slab comprising:
a conduit communicating air from under the slab to an outside area of the building, said conduit having a volume;
a fan coupled to the conduit and moving air through the conduit;
a housing;
a pressure sensor coupled to the volume between the slab and the fan through a conduit and configured to generate a pressure signal corresponding to a pressure within the volume of the exhaust conduit;
a controller coupled to the pressure sensor, the controller is programmed to compare the pressure signal to a first threshold and a second threshold, said controller generating a low pressure indicator when threshold is both at and below the first threshold and a high pressure indicator when the pressure signal is at and greater than the second threshold, said high pressure indicator indicative of a conduit problem above the exhaust fan, said low pressure indicator indicative of a problem under the slab or in the conduit below the pressure sensor; and
a wireless interface communicating the low pressure indicator and the high pressure indicator to a user device or a central monitoring system.
