PROBLEM TO BE SOLVED: To provide a sensor terminal which stops or weakens transmission or reception in a non-detectable direction before being executed by an infrared ray transceiver which is disposed by changing its angle to expand a detection space.SOLUTION: The sensor terminal incorporates a plurality of infrared ray transceivers and an acceleration sensor, so that the sensor terminal detects by the infrared ray transceivers that it faces or is close to other terminals or transmitters by transmitting and receiving infrared ray data to and from them and detects their movement or inclination by the acceleration sensor. On the basis of the acceleration data obtained by the acceleration sensor, the sensor terminal controls part or all of the plurality of infrared ray transceivers. |
