Title:
WIRELESS SENSOR SYSTEM
Document Type and Number:
WIPO Patent Application WO2005119609
Kind Code:
A3
Abstract:
A low cost, robust, wireless sensor system (100) that provides an extended period of operability without maintenance is described. The system (100) includes one or more intelligent sensor units and a base unit (112) that can communicate with a large number of sensors. When one or more of the sensors detects an anomalous condition (e.g., smoke, fire, water, etc.) the sensor communicates with the base unit (112) and provides data regarding the anomalous condition. The base unit (112) can contact a supervisor or other responsible person by a plurality of techniques, such as, telephone, pager, cellular telephone, Internet, etc. In one embodiment, one or more wireless repeaters (110-111) are used between the sensors and the base unit (112) to extend the range of the system (100) and to allow the base unit (112) to communicate with a larger number of sensors.
