Abstract
Small modules directly situated at power outlets in buildings, that contain at least one sensor gather and report local environmental data such as temperature, humidity, carbon dioxide concentration, motion, particulate matter concentration, carbon monoxide, methane, or other parameters. The local modules report data back over existing building power wiring to a central unit. The central unit may store or reduce data for reporting over to a computer over a conventional RS-232 link. The data can be used to prove compliance with environmental and safety regulations and requirements or used to control HVAC equipment. Also, the data can be displayed or used with energy price tier systems.
