1. A method comprising:
embedding a device within a construction material to generate data relating to a characteristic of the construction material; and
performing an assessment of the characteristic of the construction material in dependence upon the generated data; wherein
embedding the device comprises embedding a self-contained sensor device within the construction material comprising at least a microprocessor, a battery, a wireless interface operating according to a predetermined wireless protocol for transmitting data from the device, and a resistivity module comprising at least a porous material in contact with the construction material;
generating the data comprises allowing the porous material to reach equilibrium with a pore solution within pores in the construction material and measuring the resistivity of the porous material with the pore solution of the construction material and performing a measurement with the resistivity module;
performing the assessment comprises determining in dependence upon the resistivity measurement a measurement of the pore solution conductivity;
the characteristic of the construction material is the pore solution conductivity; and
the data transmitted by the device via the wireless interface comprises at least one of the measurement of the resistivity of the porous material or the determined measurement of the pore solution conductivity.
