Digi International has published an article where they shows how wireless sensor networks are being used to monitor fire forests, river flooding and other phenomena which were not previously detectable in real time due to their difficult-to-access nature. Sensor networks in mountains, river banks, and in harsh environments can now be deployed using the Libelium Waspmote platform. Digi sets this sensor device platform as a successful case of the use of the XBee transceivers as Waspmote that allow long range links (up to 12km in the 868MHz band) with the lowest consumption sleep mode (0.7uA). This is also crucial for other situations such as areas hit by earthquakes, floods and hurricanes where sensor networks need to be completely autonomous and robust.
