1. A sensor system comprising:
- a battery that powers the sensor system;
a radio-frequency identification (RFID) tag that stores a unique identifier of the sensor system;
a sensor that provides a sensing data for the sensor system;
an internet of things (IoT) transceiver that communicates with an access point in an IoT system;
a processor that;
receives the sensing data from the sensor; and
controls an activation of the sensor and a frequency of communication of the IoT transceiver with the access point;
a charge controller that;
controls a charging of the battery;
monitors a battery status information; and
communicates the battery status information to the processor; and
a solar cell that provides power to the charge controller,wherein, in the event that the battery status information received by the processor indicates a low battery level, the processor;
notifies the access point of the battery status information using the IoT transceiver,reduces the frequency of communication of the IoT transceiver with the access point, anddeactivates the sensor.
