WIRELESS SENSOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a thinned wireless sensor device capable of significantly reducing or eliminating the frequency of battery change. SOLUTION: A main housing A includes a glass breakage detection part 2 detecting vibration of a glass plate of a window body to detect breakage of the glass plate; an opening and closing detection part 2B detecting opening and closing of the window body; a glass breakage processing circuit 3A processing a detection signal of the glass breakage detection part 2A; an opening and closing processing circuit 3B processing a detection signal of the opening and closing detection part 2B; a radio transmitting circuit 4 including a super-wide band radio transmitting circuit transmitting a radio signal according the state of the detection signals processed by both the processing circuits 3A and 3B; and a power supply part 5 including a primary battery 1.
