The pendulum structure is hanging a heavy object by a spring, and which fixed with a plate. Thus, the heavy object can swing to any azimuth by gravity to achieve the tilt angle measuring of the two-dimension azimuth angle. The sensitivity of this tilt sensor can achieve every tilt angle "1°" in 16 azimuth angles. Furthermore, the result of Arduino will be uploaded to ThingSpeak by Wi-Fi. So, no matter computer, pad or smartphone, all can real time monitor the result of sensing project by ThingSpeak. Tsair-chun Liang 梁財春 2016 學位論文 ; thesis 83 zh-TW |
