A Low-power Wireless Remote Sensor Node Design based on GPRS
For the limitation of transmission distance and power volume of sensor node, a low-power remote data acquisition node which implements long-distance data transmission by combining General Packet Radio Service network with wireless sensor network is designed to acquire data periodically and upload data to remote server through General Packet Radio Service network. This paper expatiate hardware design principles of the node, power management model and software protocol design of the test system. Test results show that nodes can reliably acquire and upload data, the average work current of sensor node is 34mA, the peak current of cluster-head is 260mA when cluster-head uploads data to server, and sleep mode current are both less than 35uA. Performance indicators of node can fulfill the needs of remote monitoring applications in industrial field.
