Systems and methods for improved personal monitoring systems and devices include the provision of sensor data from a personal monitoring device to a server system. The sensor device is provided to the server system at a first rate and subsequently analyzed by the server system. If the server system determines that a particular condition is met based on the sensor data the server system transmits a reconfiguration message to the personal monitoring device that causes the personal monitoring device to automatically begin providing data at a second rate. Among other things, the condition resulting in generation and transmission of the reconfiguration message may include a location-based condition (e.g., crossing a geographic boundary), a change in an environmental condition (e.g., temperature or air quality), or a movement-based condition (e.g., an acceleration indicative of a fall or collision).
