Based on Multi-bus Control of the Wireless Sensor Network Nodes

摘要

In order to achieve wireless communication between sensor nodes, a multi-bus system integrated into a wireless sensor network nodes is applied with the measurement of temperature and humidity. The SPI bus, I²C bus, RS232 bus, and l-wire bus are discussed in detail, and given full play to their strengths. The master and slave of the software workflow are also introduced. The system that bases on multi-bus control of the wireless sensor network node has achieved, and can successfully and effectively monitor the environment with an emphasis on the temperature and humidity contexts.
