Touch screen based on Nurse/attendant calling system for physically impaired

ABSTRACT The aim of this paper is to develop an embedded Touch screen based nurse/attendant calling system for physically impaired by using touch sensor and GSM as wireless technology. There are many touch sensors in use today but the sensor that is used will detect the Infrared rays that are emitted from the human body. We know that in hospitals there are many situations that occur like some people are very badly wounded, injured and are in drossy condition, some of them cannot help themselves and some people can be unconscious (means they may be still alive) there will be no quick medical service to rescue them and due to the delay in the medical service people may lose their life instead when the medical service is given on time then that person can be rescued from death. In hospitals a impaired person cannot call the nurse as he is physically impaired so he will just touch the screen to intimate the nurse she is in emergency. When a human being is touch the panel sensor then it sends the signal to the microcontroller and the microcontroller sends the signal to the GSM (global system for mobile communication) this GSM sends the message to the nurse team that the patient is in emergency The code contains the registered mobile number of the nurse team. Then the nurse operation will be fast in detecting the persons who are in emergency. The nurse team can save many people life at a faster rate through this embedded system Keywords: Microcontroller AT89S52, Touch sensor, GSM, LCD, Buzzer, Power supply.
