Abstract
A sensor system for road construction equipment. The system includes a first conveyor for transporting material to a first auger that is positioned to receive the material. A first feeder sensor associated with the first conveyor is in over-the-air communication with a receiver to communicate the height of a material on the conveyor such that a master controller that is electrically connected to the receiver can regulate the amount of flow of material to the first conveyor.
