Ha Ha Humanoid!] I have specs for a PIR (Passive InfraRed detector). They are made by Raytek Inc, a member of the Hoermann Group (whoopie-doo!). 800-227-8074. Specifications: mounting: ceiling (recessed or surface) [yes I know, you don't have a ceiling over your yard so take this for what it's worth] range: 16 feet pattern: 21 degrees by 43 degrees in 10 segments input voltage: 12-24 V D.C. Current: 10 ma Output: Form C relay 1 A at 30 VDC Operating Temperature: -30 deg. F to 150 deg. F Construction: high-impact thermoplastic Dimensions: model 410 - 2-7/8 x 5" dia. model 430 - 2-7/8 x 6.5" dia. Weight: 1.5 lbs Operation and coverage: Raytek 410 and 430 Trap Detectors operate by sensing changes in infrared energy levels within the detection pattern. When a person enters the protected area his body heat abruptly changes the infrared energy level and triggers an output from the detector. The alarm relay has a built-in alarm timer. This is used to extend relay dropout time for special applications, such as access control. The relay may be held in the alarm state for any length of time between 1 and 30 seconds. The rectangular field it covers is divided into 10 zones, 5 by 2. You can select which ones to use to avoid areas which will cause false triggering.
