Implementation of building stability analyzer with earthquake detection using simple mems pressure sensor

Abstract

Analysis of building stability is an essential measurement process for all buildings in cities for achieving safety and serviceability. This is achieved by measuring the vibration of the building, and also, an alert is created to save the life of people who live in very tall building. It is proposed to design a stability analyzer combined with earthquake detection alarm. When earthquake is detected, the controller checks the vibration level with threshold level. If the vibration input exceeds threshold level, the controller triggers alarm and sends voice message through GSM. In the proposed paper, the MEMS pressure sensor (BMP180) is used to sense the vibration. In addition to sending data to monitoring section, it automatically opens all doors and sends data to nearby rescue station and emergency warning call to evacuate the people from high-rise building. The vibration of the building is recorded continuously for the proper maintenance and service.
