We come across hospitals and NGO’s serving paralytic patients who have their whole or partial body disabled by the Paralysis attack. These people in most cases are not able to convey their needs as they are neither able to speak properly nor do they convey through sign language due to loss in motor control by their brain. In such a situation we propose a system that helps disabled person in displaying a message over the LCD by just simple motion of any part of his body which has motion abilities. This system also takes care of the patient health using temperature sensor, pulse oximeter and monitoring sensor data on LCD module. If the sensor data exceed threshold value then system sending this data through RF transmitter and received by RF receiver and fed this data to the microcontroller then microcontroller send message through GSM and active the buzzer for alerts the people. Our proposed system works by reading the tilt direction of the user part. The working of the device here is shown by holding in the fingers of the mobile hand. The user now just needs to tilt the device in a particular angle to convey a message. Tilting the device in different directions conveys a different message. Here we use MEMS accelerometer in order to measure the statistics of motion. It then passes on this data to the microcontroller. The microcontroller processes the data through RF transmitter and received by RF receiver fed as this to microcontroller. The microcontroller now displays the associated message on the LCD screen. If there was no one to attend to the message displayed on the LCD, the patient can choose to tilt the device for some more amount of time which will trigger an SMS to be sent through a GSM modem to the registered care taker of the patient with the message that the patient wants to convey. In this way the Automated Paralysis Patient Care System truly automates the care taking ability of the patient which ensures a timely attention to the patient and thus for a good health of the patient..   RF Communication ranges in between 30 KHz to 300 GHz. RF communication works by creating electromagnetic waves at a source and being able to pick up those electromagnetic waves at a particular destination. These electromagnetic waves travel through the air at near the speed of light. The wavelength of an electromagnetic signal is inversely proportional to the frequency; the higher the frequency, the shorter the wavelength. The main controlling device of the whole system is a Microcontroller. The Microcontroller is loaded with an intelligent program written using embedded ‘C’ language.
