ABSTRACT:Objective To study the relationship between corrosion and environment, a realizing method of the multi-pa-rameter miniaturization monitoring node for aircraft corrosive environments was proposed in this paper. Methods Four key environmental parameters which are the major factors affecting the corrosion were selected:temperature, humidity, time of wetness ( TOW) and chloride ion concentration. And the corresponding sensors were chosen or designed for monitoring. <br> Besides, this paper introduced a miniaturization monitoring node which could realize the measurements of multiple corrosive environmental parameters. The monitoring node was based on the Texas Instruments MSP430?micro-controller and includ-ed the aforementioned sensors. Results In the end, the verifications showed that the humidity and temperature sensor, the TOW sensor, and the electrochemical sensor were available;the measurements of four parameters could be performed cor-rectly by the node. Conclusion Featuring a small volume and low weight, the node was applicable for on-aircraft corrosion monitoring. And this approach will provide actionable knowledge for aircraft maintainers, such that the aircraft safety could be driven to increased levels.
