Design of sensor and actuator network for maturity estimation in civil engineering structures

This paper describes the implementation of a wireless sensor and actuator network (WSAN) designed to reduce costs and optimize the construction workflow in civil engineering. The WSAN focuses on monitoring the maturity of huge concrete structures. Maturity monitoring is a simple and nondestructive method for estimating the strength gain of concrete structures at early stages. This technique is based on the principle that concrete strength is directly related to both its age and temperature history. The main advantage of the system is that its operation is fully automated, it is tolerant to environmental and electrical disturbances and it does not require qualified experts for its configuration or use.
