Sistema de monitoramento e controle de umidade em concretos em processo de cura

Abstract

This work proposes the development of a system to control humidity on concrete slabs on the time of cure. The objective is that maintenance of humidity, currently done manually, will occur automatically. For this, sensors is going to measurer the relative humidity inside the concrete and will send this information to a central. This central will decide whether it is necessary to get wet the structure. If the answer is positive, the central will send commands to a system of solenoid valves that allow or not a water flux on the concrete that must to be cured. This central have a microcontroller, and the sensors and system of valves too. These subsystems communicates with the central by radio waves. A LCD display shows the information of temperature and humidity in the time. The time the system stay attached is settled at beginning, and depends of the time stipulated by civil engineer responsible for the work.
