Inquiry (采购产品): seeking motion sensors I am am engineer working on building a musuem. This museum will have 3 audio/video display areas triggered by ceiling sensors. The ceiling is 13'. The square footage and shape for these 3 areas are:155' (half circle), 14' (square), 58.5' (rectangle). What products do you have that might satisfy these specs. Prefer contact closure triggering. Do you know of any sensors that might be usable in this application? Thanks, Anthony Guarneri Electrosonic Systems International 3320 N.
