Original Abstract Submitted
a system includes a radio frequency (rf) device outputting an rf signal; and at least one sensor device generating a power supply voltage using the rf signal output from the rf device, and operating by the power supply voltage, wherein the sensor device includes a case; a plurality of detectors disposed in the case, and collecting environmental data of a space in which the rf device and the sensor device are input, to generate detection data; a battery supplying a power supply voltage necessary for operation of the plurality of detectors; and a charger charging the battery, wherein the charger includes an antenna installed in the case and receiving rf power from an external source, an rf-dc converter converting an alternating current voltage corresponding to the rf power into a direct current voltage, a matching circuit connected between the antenna and the rf-dc converter, and a dc-dc converter adjusting a level of the direct current voltage and charging the battery.
