The smart wireless temperature measurement system for ships

In order to overcome the complicated electromagnetic environment in ships and implement efficient transmission of information,a type of smart wireless temperature measurement system based on TinyOS operating system is designed in this paper. Combining the ATmega128L controller chip,CC2420 RF chips and DS18B20 temperature sensor together as the wireless sensor network node,the precise acquisition and wireless transmission of temperature data is realized. Moreover, real-time monitoring, processing, storage, and alarms can be achieved through the PC software.The test of the smart wireless temperature measurement system designed for ships show that the system is able to get temperatures of test points stable,fast and accurately,and the structure of the system is simple,the layout of node is flexible and it has strong anti-Jamming,so it is applicable to complex and limited-space environment of ships.
