20130271286 | Methods and Systems for Monitoring Environmental Conditions Using Wireless Sensor Devices and Actuator Networks - The present invention comprises methods and systems of a network of sensor devices to monitor environmental conditions. Each sensor device is capable of acquiring environmental data and transmitting the data to a central controller of a networking system by wireless communication. By processing the environmental data obtained from the geographically deployed sensor devices, the central controller is capable of detecting a trend of the hazardous condition. The central controller generates early warning signals based on the hazardous levels of the physical or environmental conditions, as well as the trend of such conditions. When receiving a high level of hazardous conditions from one of the networked sensor devices, the central controller can compare the results with neighboring sensor devices to determine whether the signal received is due to a hazard leakage or a sensor device malfunction, so to reduce false alarms and provide feedbacks to communication devices networked in the system. | 10-17-2013 |
