Forest fire detection system based on Node wireless sensor Network


Forests are one of Earth’s primary air filter scrubbing the atmosphere of CO2, a greenhouse gas and contributor to global warming. Fire, whether started by natural causes, cigarettes, agricultural techniques or and other reason, is contributing to massive losses of forest land, and it is time to use technology to help Mother Nature preserve those land.A sensor network can provide the early warning necessary to allow firefighting resources to converge on the source of the fire as soon as possible By definition, a sensor network is a set of nodes or motes distributed in the forest that periodically reports data to a coordinator for processing based on Moteview software which introduce big advantages and high flexiblity and self configuration and scalability , embeded montoring and control. In a forest, hundreds of low-cost, low-power smoke detecting nodes could be distributed within wireless transmission range of the central, or coordinato node .The coordinator node would gather information from the nearby sensor nodes through a ZigBee compliant wireless network and by Moteview software provide graphics , process the data and if any smoke is detected, send out an alert using a larger wireless network, such as 3G or GPRS. This alert could be sent directly to the firefighting station, with not only fire location information but also the time of the detection. Environmental parameters such as smoke, temperature and humidity in the forest region can be monitored in real time. From the information collected by the system, decisions for firefighting or fire prevention can be made more quickly by the relevant government departments.
