ABSTRACT:
A damper assembly includes a damper frame, at least one damper blade, an actuator and a sensor module. The damper blade(s) is/are movably attached to the damper frame to at least partially regulate air flow proximate the damper frame. The actuator is configured to control a position of the at least one damper blade. The sensor module is coupled to a first damper blade and includes a sensor device operable to determine position information regarding the position of the damper blade. The sensor module further includes a wireless communication circuit that is operable to communicate the position information to a second wireless communication circuit disposed off of or away from the damper blade.
