Development of farming PDA based on the zigbee wireless sensors network and GIS

It is the basic needs for carrying out precision agriculture to acquire the farmland information in real-time. Farming PDA is developed based on wireless sensors network and GIS technology. Farming PDA integrates the Zigbee coordinator module, GPSOEM module, GPRS module, and embedded GIS module as a whole mobile intelligent farming solution. Zigbee module is used for coordinating and managing the field wireless sensors network and for collecting the farmland information through the network. GPS module is used for collecting and managing the geographic location information of each sampling point and for collecting the boundary geographic information of the target sampling field. GPRS module is used for the remote communicating and transferring the farmland information between the farming PDA and the host PC. The farming PDA can exchange information with the host PC in real-time so that it can be used to collect the farmland information in real-time.
