INTELLIGENT WIRELESS EMERGENCY ALERT SYSTEM FOR PATIENT HEALTH MONITORING USING GSM

 In case of emergency and dangerous situations we have to alert the doctor immediately. For this we are using a GSM based network for doctor to patient communication in the hospital and even to communicate and indicate the status of the patient through SMS. This way of communication is actually done with the GSM network. Each patient will be given this module and with the help of this module the patient health condition is monitored and if there is any change in the condition of the heath then it immediately sends that changed data through transfer as message to GSM to the corresponding or the relevant person. In this we check the patient’s health condition by monitoring the heart beat. The heart beat is monitored with the pulse rate of the body. The high intensity light sensor senses the expansion and contraction of the heart with the help of the nerves. That beam will transmit the signal to the receiver and the minuet change in the pulse is noticed as the heart beat. If there is any change in the pulses then it is noticed as the change in the heart and then the controller will get a disturbed pulse count which indicates the fault or malfunction of the heart. The controller is fixed for a no. of pulses initially. If there is any change in the any of the pulse count then it considers as a malfunction of the heart and then it transmits the pulse count with the patients ID to the doctor in the hospital and at the same to it sends a SMS to a fixed number in the microcontroller. After that we are adding another two sensors for human. The precision in body heat measure is +0.5degree centigrade .Measured the body heat through lm35 temperature sensor. Another sensor alcohol and smoke sensor
