The most difficult test for a PIR motion sensor is when the target walks forward to the sensor, as the geometry of the lens design is such that only a few passive beams are crossed. Response is best when the target moves circumferentially around the motion sensor, keeping a fixed distance from the unit. Also, fast motion, close to the sensor or very slow are good ways to see design shortcomings in performance.

Anyone wandering around a park at one of the sprinklers' pilot locations after the park is closed for the night will get caught in a spray of water, said Police Chief Frank Wills.
