Steven Hoff, an Iowa State University professor of agricultural and biosystems engineering, has developed a system for operating odor mitigation systems only when the weather is most likely to cause the odors to become a nuisance to neighbors. Hoff's odor mitigation prototype monitors several climate variables and operates only when neighbors may be affected. The system is a miniature weather station that includes locations of neighbors as part of its programming. "If no one is going to be impacted by the odors emitting from a pig house, let's say, or a poultry house, then save the farmer some money and don't mitigate, he says.
