Intelligent Automated Monitoring and Curing System for Cracks in Concrete Elements Using Integrated Sensors and Embedded Controllers

Crack formation and rehabilitation of concrete elements, such as slabs and columns, in buildings located in areas with temperatures above 25 °C, where accelerated water evaporation significantly reduces their structural strength, was addressed. To mitigate this effect, an intelligent automated monitoring and curing system was developed, using integrated sensors and embedded controllers. The study was applied, experimental and explanatory, based on the hypothetico-deductive method. Work was carried out with physical models (specimens, columns and solid slabs) with 1:2:3 dosage, in which thermal and humidity sensors were integrated, and a visualisation system with an LCD screen was designed in Proteus for data collection. Quantitative analysis, with 95 % confidence, revealed a moderate and significant correlation (r = 0.587; p = 0.001) between the environmental thermo-hygrometer and the embedded DS18B20 sensor, showing effective heat transfer. The low correlation with the HD-38 sensor (r = 0.143; p = 0.468) indicated little influence of ambient humidity on internal humidity. The system restored the initial screams, used 1680 litres of water in 28 days, reducing consumption by 20 % compared to traditional methods. Higher evaporation was identified between 11:00 and 16:00 hours (UTC-5), a critical phenomenon not reported in previous studies in tropical areas.
