Portable monitoring unit
First Claim
1. A sensor system, comprising:
- one or more sensor units, each of said one or more sensor units comprising at least one sensor configured to measure a condition, said sensor unit configured to receive instructions, said sensor unit configured to report a severity of failure value when said sensor determines that data measured by said at least one sensor fails a threshold test, said sensor unit configured to adjust said threshold from time to time according to sensor reading taken during a specified time period;
a base unit configured to communicate with said one or more sensor units to a monitoring computer, said monitoring computer configured to send a notification to a responsible party when said severity of failure value corresponds to an emergency condition, said monitoring computer configured to log data from one or more of said sensor units when said data from one or more of said sensor units corresponds to a severity of failure value; and
a portable monitoring unit comprising;
a controller in communication with said one or more sensors, said controller configured to allow a user of said portable monitoring unit to remotely set a sensor threshold level of said one or more sensor units, said controller further configured to receive one or more actual sensor data threshold levels from said one or more sensor units;
a display;
one or more input devices; and
a transceiver configured to provide communication between a sensor system and said controller.

Abstract
A sensor system that provides an adjustable threshold level for the sensed quantity is described. The adjustable threshold allows the sensor to adjust to ambient conditions, aging of components, and other operational variations while still providing a relatively sensitive detection capability for hazardous conditions. The adjustable threshold sensor can operate for extended periods without maintenance or recalibration. A portable monitoring unit working in communication with the sensor system provides immediate communication of conditions detected by the sensors. The portable monitoring unit allows building or complex management to be in communication with a sensor system at all times without requiring someone to be physically present at a monitoring site. The portable monitoring unit can be equipped with an auditory device for alerting management or a screen for displaying pertinent information regarding an occurring situation so that management can quickly identify and resolve the problem. In addition, the portable monitoring unit can also be equipped with function keys that allow the portable monitoring unit to send instructions back to the sensor system. In one embodiment, the portable monitoring unit also includes a second transceiver for communications over a short wave radio frequency, or with a cellular phone system.
