Arduino application to measure the moisture content in cement mortars

The way of measuring moisture in construction materials has evolved gradually. However, the study of moisture in building materials continues to have a problem in construction. The use of alternative sources for natural aggregates is becoming increasingly important [1]. More recently, sensors are increasingly being used to measure and characterize physical parameters such as temperature, relative humidity, moisture, among others. They have appeared as a promising way to monitor the behavior of the materials in building structures. This paper suggests the Arduino as a platform to manage the information from the sensors, in order to use that information to evaluate the behavior of the physical parameters and predict any issue in structures of buildings. After appraising the results can be defined prevention plans or in other case correctional plans but with enough time to act and maintain or repair any damage on the structures. Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical and digital world. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards or breadboards and other circuits. The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs from personal computers. The microcontrollers are typically programmed using a dialect of features from the programming languages C and C++. The Arduino project started in 2003 as a program for students at the Interaction Design Institute Ivrea, Ivrea, Italy aiming to provide a low-cost and easy way for novices and professionals to create devices that interact with their environment using sensors and actuators [4]...
