An HVAC sensor is provided that includes a housing that houses a sensor. In some instances, a conduit is provided that has a first end that extends out the back of the HVAC sensor housing and adjacent to (and sometimes through) a hole in a duct of the HVAC system that is situated behind the HVAC sensor. The sensor itself may be positioned adjacent the other end of the conduit outside of the duct, and sometimes inside the housing of the HVAC sensor. The conduit may direct pressurized air emanating from the hole in the duct toward the sensor, thereby allowing the sensor to sense a parameter of the air in the duct without actually positioning the sensor within the duct.
