In connection with the global trends of increasing requirements for efficiency and environmental friendliness of production, to create the safest possible conditions, innovative technologies are more intensively developed and applied. Today, an urgent issue is the improvement of systems for monitoring the construction of buildings and structures. The study presents an embedded sensor for non-destructive wireless control of reinforced concrete structures by the Maturity method, which allows monitoring data on the current concrete strength gain and internal temperature using special software. The features of the device, consisting of three main components: temperature gauges, a data collection station, and server software are disclosed. Experimental studies on debugging the sensor operation are presented. The test results presented in the work confirm the characteristics and functionality of the sensor. Thus, the strength values of concrete samples obtained by embedded sensors showed a greater convergence (R2 = 0.9357) with fundamental compressive strength values, compared to those obtained by the Shock-pulse method (R2 = 0.8965). Application of the proposed solution may significantly optimize the concrete formwork removal cycles speeding up the pace of construction, saving man-hours and other resources, including finances.
