Sensor device

The present disclosure relates to a communication device and a communication method that enable adaptive positioning. A communication unit performs wireless communication with a peripheral communication apparatus, and a processing unit outputs, on the basis of a frequency characteristic of a propagation channel, information of a distance to the communication apparatus and reliability level information representing a reliability level of the distance information. The present disclosure can be applied to, for example, a BLE chip.

Communication device and communication method

A sensor apparatus includes a sensor head and a measurement unit. The sensor head includes a first probe and a second probe. The first probe includes a first tiny antenna section for transmission and a second tiny antenna section for transmission. The second probe is arranged at a predetermined distance from the first probe, and includes a first tiny antenna section for reception and a second tiny antenna section for reception. The measurement unit generates a measurement signal that includes information regarding characteristics of a propagation of an electromagnetic wave in a medium between the first tiny antenna section for transmission and the first tiny antenna section for reception, and information regarding characteristics of the propagation of the electromagnetic wave in the medium between the second tiny antenna section for transmission and the second tiny antenna section for reception. The first probe and the second probe have different probe lengths, or a distance between the first tiny antenna section for transmission and the first tiny antenna section for reception, and a distance between the second tiny antenna section for transmission and the second tiny antenna section for reception are different from each other.

Sensor apparatus and water amount measurement apparatus

A measurement device that measures an amount of moisture in a medium. The device includes a transmitter that transmits an electrical signal including an incident wave to one of a pair of probes in which a cable has been embedded through the cable. A receiver receives a reflected wave obtained from reflection of the incident wave by the one of the pairs of probes and a transmitted wave that has been transmitted through a medium between the pair of probes through the cable. A processing unit obtains a reciprocating delay time corresponding to a time over which the electrical signal reciprocates through the cable and measures an amount of moisture contained in the medium on the basis of the reciprocating delay time and a propagation transmission time corresponding to a time over which electromagnetic waves propagate and the electrical signal is transmitted through the medium and the cable.

Measurement device, measurement system, and measurement method
