A sensing device includes a shell comprising an elastomeric material, the shell including a first portion having a first end and a second portion having a second end. The shell may be egg-shaped. The first portion includes a conducting disc and a plate that includes a temperature sensor, a location sensor, and a micro-fiber composite sensor. The first portion also includes an antenna and a first electrode extending through a first hole in the first portion of the shell. The second portion includes a quantity of a metallic substance embedded on the inside surface of an end of the second portion, and a second electrode extending through a second hole in the second portion of the shell. The sensing device may be inserted into a concrete mixture, Obtain measurements relating to the concrete mixture, and transmit data to a database. |
