LOW POWER WIRELESS SENSOR NETWORK FOR BUILDING MONITORING

Abstract• Analysis of the stability of the building is a needed
measurement process for all buildings in the cities. Periodic monitoring of the structure for such damage is therefore a key step in rationally planning the maintenance needed to guarantee an adequate level of safety and serviceability. However, in order for the installation of a permanently installed sensing system in buildings to be economically viable, the sensor modules must be wireless to reduce installation costs, must operate with a low power consumption to reduce servicing costs of replacing batteries, and use low cost sensors that can be mass produced such as MEMS sensors.
Existing System
• There is no proper system for measuring the stability of the buildings hence we go for the proposed system.
Proposed System
• In this project we have MEMS accelerometer to sense the shaking of the building which in sends to the microcontroller which in turn sends to the monitoring section through Zigbee wireless technology. Here we have three sections, the two floor sections has PIC microcontroller, Zigbee device and MEMS accelerometer. The monitoring section has PC and a Zigbee wireless device, which will collect the data from the floor sections and analyze the stability of the building.

MPLAB
• MPLAB® X IDE is a software program that runs on a PC (Windows®, Mac OS®, Linux®) to develop applications for Microchip microcontrollers and digital signal controllers.
• It is called an Integrated Development Environment (IDE), because it provides a single integrated “environment” to develop code for embedded microcontrollers.
• MPLAB® X Integrated Development Environment brings many changes to the PIC® microcontroller development tool chain. Unlike previous versions of MPLAB® which were developed completely in-house, MPLAB® X is based on the open source NetBeans IDE from Oracle.
• Taking this path has allowed us to add many frequently requested features very quickly and easily while also providing us with a much more extensible architecture to bring you even more new features in the future.
Features
• Provides a new Call Graph for navigating complex code• Supports Multiple Configurations within your projects• Supports Multiple Versions of the same compiler• Support for multiple Debug Tools of the same type• Supports Live Parsing• Import existing MPLAB® 8 projects and use either IDE for the same source.• Supports hyperlinks for fast navigation to declarations and includes• Supports Live Code Templates• Supports the ability to enter File Code Templates with license headers or
template code• MPLAB® X can Track Changes within your own system using local history• Within MPLAB® X, a user can configure their own Code Format Style
