Design and simulation of mems sensors with inbuilt GSM Communication for smart buildings

Abstract

Use of MEMS based sensor in building automation is a trend in the present. This is because the inherent behavior of MEMS sensors are being very compact, low powered, sensitive and cheap methods of sensing biological and environmental activities in a smart building. This paper discusses about the use of MEMS based acceleration sensor and a pressure sensor coupled with an inbuilt GSM module in the building automation system, particularly the security applications. The writers have decided about the parameters for the needed sensors and designed the pressure sensor and the acceleration sensors for fabrication accordingly. The conceptual system hardware was tested using commercially available sensors and GSM modules. The applicability and the methods the integrated sensor system can be used for is also discussed. The case study is performed at the premises of The Sri Lankan Institute of Nanotechnology (SLINTEC). The paper contains the design parameters and the electronic systems design data and drawings. It is hoped that this data would be supportive to any person who would design or improve the proposed system.
