Abstract: Systems and methods for operating a wireless sensor monitoring system are provided. The sensor monitoring system includes one or more portable sensor devices deployed at a remote location. The system also includes a controller server configured to automatically detect the one or more portable sensor devices via a network connection, to receive sensor data from the sensor devices, process the sensor data using user-defined rules, and to send commands to the sensor devices instructing the devices to perform various actions. The controller server is further configured to provide a user interface for accessing sensor data from the portable sensor devices, generating a map interface of the remote location that displays the positions of the sensor devices, for receiving rule definitions to actions to be taken at specific times or if specified events occur, and for generating alerts and reports from sensor data.
