Abstract: For farmland environmental conditions， monitoring is difficult， a farmland information monitoring system based on WIA-PA was designed. The system used sensor nodes to collect the farmland environmental parameters and send them to remote server by WIA-PA. The remote server analyzed and stored the parameters， and informed the manager of the data exceed an established threshold in time. The manager can send the control command to the sensor nodes to adjust the relevant parameters， and thus realize the remote measurement and control. The tests indicated that the system runs well with small consumption and good application value.
