摘要
A system includes a sensor device having a sensor adapted to generate measurement data relating to a characteristic of a concrete mixture, a transmitter adapted to transmit a first signal based on the measurement data, and a conductive wire forming a coil having a plurality of loops around the sensor device and a wire antenna. The coil is adapted to generate an electric current in response to the first signal. The antenna is adapted to transmit a second signal based on the electric current. The system is embedded in a concrete mixture and a portion of the antenna is exposed above the surface of the concrete mixture. A current is induced in the coil due to electromagnetic induction. A second signal is transmitted via the wire antenna. The second signal is received and transmitted to a processor. The processor may analyze and/or store the signal.
