US Patent 10905057 Thermal imaging drift sensor for agricultural spraying

Wind speed, wind direction, and field boundary information are detected and used to identify a monitor area indicative of a likely overspray condition. Control signals are generated to obtain information from a sprayed substance sensor, in the monitor area. When an overspray condition is detected, an overspraying signal from the sprayed substance sensor indicating the detected overspray condition is received and overspray processing is performed, based upon the received overspray signal.
