A WIRELESS SENSOR NETWORK FOR MONITORING ATMOSPHERIC AGGRESSIVENESS IN METALS

Humid tropical climate favours the existence of a corrosive atmosphere that causes deterioration of metals. This article describes an automated system for monitoring environmental values (temperature and relative humidity) in order to know the time of wetness (TOW), which is key factor in determining the atmospheric aggressiveness which are exposed the metals used, for example, in industrial facilities. System is implemented on a wireless sensor network and the main function of the software developed is to count the time of wetness which is considered the effective time in which metals corrode. System was designed considering the user requirements as the selection of the frequency of measurements, the calculation of TOW and verification of the residual energy of sensor nodes. The results show the effectiveness of the technology used, so that, we can conclude that this type of networks represent a feasible alternative for automated monitoring of corrosion in metals.
