A method for operating an automatic liquid spray system for dust mitigation on a work machine can include receiving, with a controller, a signal from a sensor attached to a frame of the work machine. The signal can be indicative of dust around the work machine. The controller can include a location of the sensor on the frame. The method can also include sending a signal to a dust mitigation system. The signal can be indicative of the location of the sensor such that the dust mitigation system can control a liquid control module to provide liquid to a dust mitigation valve around the location of the sensor on the frame. The method can also include opening, with the dust mitigation system, the dust mitigation valve around the location of the frame around the sensor to provide liquid around the location of the sensor.
