Wireless sensor monitoring unit
First Claim
1. A wireless sensor monitoring unit, comprising:
- a base unit configured to communicate with one or more sensor units, said monitoring computer configured to send a notification to a responsible party when data from one or more of said wireless sensor units corresponds to an abnormal condition, said monitoring computer configured to log data from one or more of said wireless sensor units when said data from one or more of said wireless sensor units corresponds to an abnormal condition, said base unit configured to send an acknowledgements to acknowledge receipt of sensor data from said one or more wireless sensor units, each of said one or more wireless sensor units comprising at least one sensor configured to measure an ambient condition, said wireless sensor unit configured to receive instructions;
said wireless sensor unit configured to report data measured by said at least one sensor when said wireless sensor determines that data measured by said at least one sensor fails a threshold test, said one or more wireless sensor units operating in a low-power mode when not transmitting or receiving data, said one or more wireless sensors configured to transmit status information at regular intervals;

Abstract
A low cost, robust, wireless sensor system that provides an extended period of operability without maintenance is described. The system includes one or more intelligent sensor units and a base unit 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 and provides data regarding the anomalous condition. The base unit 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 are used between the sensors and the base unit to extend the range of the system and to allow the base unit to communicate with a larger number of sensors.
