Movement based and Voice enabled Device Switching for basic needs of Physically Challenged Persons
B. Ramana Reddy | J. V. Sharma
Abstract: The main aim of this project is to provide the basic needs for physically challenged persons like food, water and medicine and to control the electrical devices like Fan, bulb by using switch buttons and also for controlling wheel chair by using MEMS technology. MEMS are a micro electro mechanical sensor which is a highly sensitive sensor capable of detecting the tilt. This device is portable and this system operation is entirely driven by wireless technology. User can wear the MEMS to his finger and can operate it by tilting up, down, left and right side respectively. This system is also makes use of Microcontroller like LPC2148. This project also makes use of switches which are operated by physically challenged persons to control the electrical appliances like fan, bulb and some other devices Using AT89S52 Micro Controller and wireless technology like Zigbee. Here one zigbee is placed on Wheel chair and another Zigbee with AT89S52 microcontroller is connected to all electrical appliances. These switches can also be used to control APR 9600 for audio announcement which is programmed with the help of embedded c instructions.
