The grain depot temperature measurement system's research based on wireless sensor networks

In order to ensure that the food grain storage security, while the smallest energy consumption of monitoring system, designed to application in grain depot monitoring system by clustering technology of wireless sensor networks (WSN). Designed to MSP430 MCU and CC1100 RF chip modules at the core ultra-low power node, the use of hierarchical structure of the networks is divided into a number of clusters methods, which constitute energy-efficient grain temperature of monitoring system. This method greatly reduces between the nodes and sink nodes (Sink) to transmit data the energy consumption, extension take data as core WSN life cycle, so that the whole wireless sensor networks to maximize the life span.
