Abstract
A communication system includes a master device and a slave device. The master device can transmit a signal to a slave device. The slave device includes an antenna, a sensor unit, an RFID unit, a changeover switch that connects the antenna to one of the sensor unit and the RFID unit, and a switching circuit that switches the changeover switch based on a switching signal transmitted from the master device. When the antenna in the slave device receives the switching signal from the master device, the switching circuit switches the changeover switch in the slave device from a state in which the antenna and the sensor unit are connected to a state in which the antenna and the RFID unit are connected, in accordance with the switching signal.
