Mentally Challenged people can suffer from multiple impairments that interfere with cognitive function. Mentally challenged people living in hospitals may go missing unknowingly. Therefore, it is very important for the hospital authorities to constantly monitor the patients. This project is designed to alert the hospital authorities about the patients, who tries to exit the hospital premises, with the help of wireless communication. This project consists of tracking & monitoring unit, control unit & display unit. The tracking & monitoring unit is designed using RF transmitter, RF receiver, ZigBee module, GPS & GSM module. ARMLPC2148 controller is used for the control unit. The global positioning system (GPS) tracks the patients & sends an alarm signal to the control room, when the patient crosses the hospital premises. Also, the exact location & time of exit of the patient is displayed in the display unit. An alert SMS is also sent to the concerned medical supervisor about the missing patient using GSM. Embedded C is used for programming the ARM Microcontroller.
