SYSTEM AND HOME APPLIANCES CONTROL USING MEMS ACCELEROMETER
ABSTARCT :
Present industry is increasingly shifting towards automation. Two principle components of today’s industrial automations are programmable controllers and robots. In order to aid the tedious work and to serve the mankind, today there is a general tendency to develop an intelligent.
As the name signifies, an embedded system is embedded or builds into something else. Embedded system encompasses a variety of hardware and software components, which perform specific functions in host system, for example satellites, washing machine, automobiles. Embedded system has become increasing digital with a non digital peripheral and therefore both hardware and software coding signs are relevant. Most embedded control product must special requirement, cost effectiveness, low power, small-footprint and a high level of system integration.
EXISTING SYSTEM :
• Accelerometers are generally used in mobiles, vehicle, health monitoring application.
• Most of the system was generally controlled by wired mouse, in case any failures occur in physical components like wires the mouse does not work.
• Now a days Bluetooth mouse also available it covers only 10-20 meters.
• Bluetooth mouse operating voltage is 5v but the ZigBee operating voltage is 3.3v so the power consumption is less compare to Bluetooth
DISADVANTAGE :
Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems.
PROPOSED SYSTEM :
• Day by day the technology is improving in this world, compare to ZigBee the Bluetooth is older one. so this project done by using ZigBee technology.
• In this project the system is controlled by hand movements(accelerometer).
• In this project ZigBee technology is using because it covers more distance compare to Bluetooth technology.
• It not only performs the normal mouse operation also perform the keyboard operation (by using Visual Keyboard).
• In this project the circuit is also control the home appliances by using hand movements
ADVANTAGE :
• Power consumption is less.
• Cover more distance compare to Bluetooth.
• Easy to implement.
