The inclusion of internet communication within the loop of control is innovative comparing with the design methodologies of classical control system. In the proposed system, hazardous environment monitoring and control for monitoring information concerning safety and security, utilizing Wireless Sensor Network (WSN) technology. The proposed hazardous environment monitoring and control collects environmental parameters inside the laboratory through WSN-based sensors, collects image information through vision system. The sensor manager manages information collected from the WSN sensors and the image information manager manages image information collected from vision system of the hazardous environment.
