The National Electrical Manufacturers Association has published NEMA WD 7-2011 (R2016) Occupancy Motion Sensors Standard, which promotes uniformity in the use and application of occupancy motion sensors used in lighting control systems, HVAC, and other devices. This standard explains field of view and coverage characteristics relevant to vacancy and occupancy sensors using passive infrared, ultrasonic, or microwave technology.

NEMA re-released Occupancy Motion Sensors Standard without changes, reaffirming the document’s technical relevance to today’s wireless device industry.

NEMA WD 7-2011 (R2016) is available in hard copy for $44 or as an electronic download at no cost on the NEMA website.
