Application of WSN in precision forestry

In order to conveniently access information of forestry, a new technology, wireless sensor network is introduced in precision forestry applications. A forestry information monitoring system based on wireless sensor network technology is proposed, which can sample temperature, soil moisture, light intensity, nitrogen concentration and other environmental factors. The networks of sensor nodes are managed by a central node which collects and transmits data to remote host computer through GPRS. The system design methodology based on ZigBee chip 2430 is presented and the corresponding system hardware architecture and software flow are given. This system effectively makes it easy to collect and transmit data of environmental factors in forestry product and posses high practical values.
