WIRELESS SENSOR DEVICE AND WIRELESS SENSOR SYSTEM

To provide wireless sensor devices in which noise from a power supply signal, a sensor element control signal, and a detection data signal does not affect a detected value during a sensing period by a sensor element.SOLUTION: A wireless sensor device 200 comprises: a first transmission/reception unit 100 that wirelessly transmits a power supply signal and a sensor element control signal to a second transmission/reception unit 110 and wirelessly receives a detection data signal of sensor elements 60 from the second transmission/reception unit 110; the second transmission/reception unit 110 including the sensor elements 60, and a memory unit 50 for storing the detection data signal of the sensor elements and timing data; and a timing control unit 40 that controls the power supply signal, the sensor element control signal, the detection data signal, and their respective timings during a sensing period, based on the timing data, so that the noise from the power supply signal, the sensor element control signal, and the detection data signal does not affect the detection during the sensing period by the sensor elements 60.SELECTED DRAWING: Figure 1 【課題】 給電信号、センサ素子制御信号および検出データ信号によるノイズが、センサ素子によるセンシング期間中の検出値に影響を与えない無線センサ装置を提供する。【解決手段】 無線センサ装置２００は、給電信号及びセンサ素子制御信号を第２送受信部１１０に無線送信するとともにセンサ素子６０の検出データ信号を第２送受信部１１０から無線受信する第１送受信部１００と、センサ素子６０とその検出データ信号及びタイミングデータを記憶するメモリ部５０と、を含む第２送受信部１１０と、給電信号、センサ素子制御信号及び検出データ信号によるノイズが、センサ素子６０によるセンシング期間中の検出に影響を与えないように、タイミングデータに基づいて、給電信号とセンサ素子制御信号と検出データ信号とセンシング期間のそれぞれのタイミングを制御するタイミング制御部４０と、を備える。【選択図】 図１
