Integrated Building Management Sensor System

A building management system comprising an integrated sensor and control system integrated on a single application specific integrated circuit (ASIC). The ASIC combines sensor inputs necessary to monitor ambient light levels, light color, occupation/motion sensors, security sensors, temperature and humidity, barometric pressure, smoke and toxic substance sensors, and a processor to receive the sensor inputs and deliver control output signals to effect changes and make settings to each of the environmental systems that are monitored. The ASIC also provides communication and control security for the building management system, preventing hostile intrusions into the system. The storage, intelligence and processing all reside within the ASIC.
