Wildfire Watch Sensor Network recently deployed in the Poudre River Canyon in northern Colorado using our Level One Sensor.


Each sensor detects the air temperature every minute in the immediate area, which may be near a public campfire area or simply in the middle of a deep forest.  Those data are then sent to the Coordinator or Base Station, which is connected to the Internet by cell phone or other means.  If the sensor is too far from the Coordinator Base Station (i.e, out of range), the transmitted data connect with the nearest sensor in the network and the data from both sensors are then sent ultimately to the Coordinator Station.  Data are then sent via the Internet to the Wildfire Watch Data Processing Center where the data are analyzed using artificial intelligence to see if a trigger temperature has been reached relative to the usual temperature regime for that location and for that time of year.  A trigger temperature indicates the likely incidence of a wildfire and sends an automated alert to Wildfire Watch headquarters and to whomever else needs to know:  a fire marshal, park ranger, house owner, or concerned citizen.  Anybody who needs or wants to know can receive the alerts.
You can see that by using this wireless mesh network approach in which not all sensors need to be within range of the Coordinator Base Station,  you can cover huge areas of forest.  Although you could cover a wide area with relatively few sensors, the more sensors you have within the network, the quicker you will receive an alert of a likely wildfire.
