A Switch Activated Environmental Control System

Abstract

            The Touch of Independence (TI) was designed to provide independence by allowing a severely handicapped person some level of control over their surroundings. The device provides wireless RF remote control of any AC powered devices within a range of approximately 40 feet. This is accomplished using a system comprised of a single PIC 12F509-based transmitter module and a pair of PIC 12F509 microcontroller-based receiver modules. The microcontrollers encode and decode the inputs, while a matched transmitter/receiver set of 434 MHz RF devices provide the wireless link. On the receiver end, a solid state relay provides the actual control of a given AC-powered device. As a whole, the TI provides the client with the ability to control the devices in their immediate surroundings.
