METHOD AND APPARATUS FOR DETECTING WATER LEAKS
First Claim
1. A system for detecting water leaks, comprising:
- a moisture sensor;
a water level sensor;
a water temperature sensor;
a processor configured to collect moisture readings from said moisture sensor, water level readings from said water level sensor, said processor configured to report a possible water leak and an identification code when said moisture sensor detects moisture above a moisture threshold value, said processor configured to report a water leak and an identification code when said water level reading exceeds a water threshold value; and
a radio-frequency transceiver configured to receive at least a command to set said water threshold.

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.
