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.
