RADIO MODULE, RADIO TEMPERATURE SENSOR, RADIO INTERFACE DEVICE, AND RADIO SENSOR SYSTEM

摘要

There is provided a radio temperature sensor which is attached to a body surface of a person who needs care for measuring the person’s body temperature. The radio temperature sensor can measure the body temperature of a person who needs care and moves around in a facility. The radio temperature sensor includes a radio function for transmitting measured data via a chip antenna. The chip antenna is formed with an antenna length of a reduction ratio that can be contained in a container. Moreover, there is provided a radio interface device having a radio communication function arranged on a compact flash (trade mark) card which reduces the carrier frequency, reduces the size of the antenna, increases the communication distance, and reduces the power consumption. Moreover, there is provided a radio sensor system in which a sensor reports the environment information around the installation place by a radio communication machine and a base station collects environment information from a plurality of sensors.
