Abstract: A system includes a sensor device for monitoring properties of a building material within which the sensor device can be embedded. The sensor device has a controller, a memory associated with the controller, one or more sensors communicatively connected to the controller for measuring one or more properties of the building material, and a power supply for powering components of the sensor device. The power supply includes a capacitor and a power regulator. The sensor device includes a power management subcircuit for activating the power regulator for powering “ON” components of the sensor device via the capacitor, wherein the power management subcircuit receives an activation signal from an external power source to activate the sensor device, and wherein the external power source is configured to charge the capacitor.
