Self-contained sensor package for water security and safety

摘要

Disclosed is a floating sensor system having a casing that encloses a microcontroller. The microcontroller includes a digital processor and a non-volatile memory. The casing also encloses a data bus that connects the microcontroller to an external environment sensor, an RF transceiver, and a battery. The non-volatile memory includes a history file that maintains a record of events sensed by the external environment sensors. The digital processor is configured to establish a pattern of expected external environmental behavior based on the record of events. The digital processor is also configured to emit a signal through the RF transceiver from the system when an unexpected event occurs.
