Document Type and Number:
WIPO Patent Application WO/2015/029794
Kind Code:
A1
Abstract:
[Problem] To provide a wireless sensor device that is capable of stably detecting a subject to be detected. [Solution] A wireless sensor device (100) is provided with an antenna (10), a transmission circuit (20), a first transmission line (31), a second transmission line (32), a first switching means (41), a second switching means (42), a first detector circuit (51), a second detector circuit (52), a first signal processing circuit (61), a second signal processing circuit (62) and a control circuit (70). From between the first transmission line (31) and the second transmission line (32), the control circuit (70) controls the selection of the transmission line for connecting the antenna (10) and the transmission circuit (20), and the switching between the first transmission line and the second transmission line. The first detector circuit (51) and the second detector circuit (52) are connected to the first transmission line (31) and the second transmission line (32), respectively. The first signal processing circuit (61) is connected to the first detector circuit (51), and the second signal processing circuit (62) is connected to the second detector circuit (52).
