Patient Monitoring and Alert System using GSM

This project includes the branch of Biomedical Engineering. This project aims at monitoring the patient’s health conditions continuously. The parameters like the pulse rate, temperature are to be monitored continuously. In other words, the doctor will be diagnosing the patient continuously. This project uses the wireless concept, GSM.

It is required to monitor the patient’s temperature, heartbeat & if the temperature increases above certain level injection has to be given. Our system does the same a sensor is used to monitor the patient’s temperature. A microcontroller is used to get the patients temperature & display it on LCD.

The modem provides the communication interface. It transports device protocols transparently over the network through a serial interface. The GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves.

The doctor can continuously check the patient’s status by just sending a predefined message to the GSM modem. The modem will be interfaced with the microcontroller through serial interface. The modem intimates the same to the microcontroller. The controller reads the various parameters from different sensors, processes them and sends the information to the modem. The modem transfers this data to the doctor’s mobile. Thus, the doctor can take immediate actions based on the parameters received from the system using GSM modem.

The system internally sets default values. If the patient’s health parameters exceed the default values, the system also alerts the buzzer and sends the information to the doctor’s mobile.
