The main aim of this project is to control the devices and to ask the basic needs like water, food or medicine by using MEMS (Micro Electro-Mechanical Systems) technology. MEMS is a Micro Electro Mechanical Sensor which is a highly sensitive sensor and capable of detecting the tilt. This sensor finds the tilt is to the right side then the device will be on for the first time then next time it will be off. In the same way, if the tilt is to the left side then another device is going to be controlled. The tilt is in upwards or downward direction the related need will be announced. This device is very helpful for paralysis and physically challenged persons. This device is portable and this system operation is entirely driven by wireless technology. User can wear it to his head like a band and can operate it by tilting the MEMS sensor. This project makes use of a Relay for switching the devices and APR-9600 voice chip for audio announcements and Micro controller, which is programmed, with the help of embedded C instructions. The MEMS based sensor detects the tilt and provides the information to the microcontroller. And the controller judges whether the instruction is right movement or left movement instruction and controls the operation respectively.
