1. A UV disinfection device comprising:
a housing having two, opposite lateral ends and a midpoint;
a UVC light source disposed within the housing;
a dual passive infrared sensor system including two passive infrared sensors, one passive infrared sensor being disposed on one side of the housing midpoint and the other passive infrared sensor being disposed on the other side of the housing midpoint;
a control system configured to:
receive sensor output from the two passive infrared sensors of the dual passive infrared sensor system,
take a difference between the sensor output from the two passive infrared sensors of the dual passive infrared sensor system,
detect an event pattern based on the difference between the sensor output from the two passive infrared sensors of the dual passive infrared sensor system, wherein the event pattern is indicative of position of human activity in a target disinfection area of the UV disinfection device, and
control operation of the UV-C light source based on the detected event pattern.
 
17. A UV disinfection method comprising:
providing a UV disinfection device having a housing, a UV-C light source, a control system, and two passive infrared sensors;
sensing passive infrared sensor output from the two passive infrared sensors;
taking a difference between the sensor output from the two passive infrared sensors,
detecting an event pattern based on the difference between the passive infrared sensor output from the two passive infrared sensors, wherein the event pattern is indicative of position of human activity in a target disinfection area of the UV disinfection device; and
controlling operation of the UV-C light source based on the detected event pattern.
