Final year projects Engineering/ Diploma/ BCA/ MCA Contact 9448847874 Vensoft Technologies is a Electronic Design Services (EDS) for VLSI / EMBEDDED and MATLAB, delivering a wide variety of end- to -end services, including design, development, & testing for customers around the world. With proven expertise across multiple domains such as Consumer Electronics Market, Infotainment, Office Automation, Mobility and Equipment Controls. Vensoft Technologies is managed by Engineers / Professionals possessing significant industrial experience across various application domains and engineering horizontals.Our engineers have expertise across a wide range of technologies, to the engineering efforts of our clients. Leveraging standards based components and investments in dedicated test lab infrastructure, we offer innovative, flexible and cost-effective services and solutions. “We are sure you don’t want to say “This is what I said but not the one I want” when we deliver. So before we start any custom application development project, we always ask our client to define scope of the project. Without having defined scope, you will not be able to measure whether we have satisfied your requirements. It does not mean that it is your duty to give us defined scope. We are here to help you with that. Our experts will be in touch with you during this phase and prepare requirement spects and get it signed from you once you are happy with the same.” Contact Us Mob: 9448847874 Mangalore 4th Floor Vasudev Towers Hotel Satkar Building Near Bus stand BC Road-574219 http://vensofttechnologies.wordpress.com/ http://www.ieeedeveloperslabs.in/ Email: vensoftprojects@yahoo.com Mobile number: 9448847874 8051 PIC16 ARM7 renesas gsm gps zigbee ethernet touchpanel thermal printer webcam image processing communication based m.tech projects

SAFETY OF VALUABLE ITEMS USING ZIGBEE AND
MEMS SENSOR
ABSTRACT:
The main objective of this project is to develop an embedded system based anti
theft alarm based on MEMS sensor and zigbee technology. This project is implemented
on an avr based Atmega16 developed board interfaced with MEMS, Buzzer and LCD for
display purpose. Micro electromechanical systems (MEMS) is the technology of the very
small, and merges at the nano-scale into nano- electromechanical systems (NEMS) and
nanotechnology.
MEMS are also referred to as micro-machines or Micro Systems Technology -
MST. MEMS are made up of components between 1 to 100 micrometers in size and
MEMS devices generally range in size from 20 micrometers to a millimeter. They usually
consist of a central unit that processes data, the microprocessor and several components
that interact with the outside such as micro sensors. Due to MEMS large surface area to
volume ratio, surface effects such as electrostatics and wetting dominate volume effects
such as inertia or thermal mass.
This property is used to detect any motion or change in acceleration due to gravity
or simply called G force. The system needs to be secured and at the same time, should be
protective for valuable items such that no body can try to theft our valuable items. The
present project deals with designing an activation system for the protection of valuable
items by checking the change in G force. If motion or change is detected the protection
system is activated. The system uses a compact circuitry build around flash version of
amega16 micro controller with a non volatile memory Programs are developed
andcompiled using avr studoi4 tool. Isp is used to dump the code into micro controller.
This project uses regulated 5v, 750ma power supply. 7805 three terminal voltage
regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify
the ac output of secondary of 230/18v step down transformer.
