The implement of the stored-grain grossness remote monitoring system based on GPRS and ZigBee

According to the actual demand of the system, the paper proposed scheme and implement for the stored-grain grossness remote monitoring system based on GPRS and Zigbee. The test result is shown that the max error is ∼0.02mA between inversion value of the server-side data and the measure value. The design should be served as the useful reference to the study of acquisition technology in similar system.
