Abstract
The project deals with the design and development of hardware and software for temperature and heartbeat measurement of a patient over GSM mobile.
The data which are recorded continuously in this project are Heartbeat and Temperature. This analog quantity is taken and converted into corresponding digital values using ADC. This converted digital value is sent to the microcontroller. The microcontroller temporarily stores this value.
The temperature and heartbeat pulses can be sent to the doctor at regular intervals or the doctor can ask the controlling unit to send the parameters whenever he requires to know the patient condition. 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 has to send predefined messages to the modem to retrieve the data. The modem receives the predefined messages and intimates the same to the microcontroller. Now, it is the job of the microcontroller to read the value from ADC, process it and send the requested value to the user mobile. The user can read the updated data whenever he reads the predefined messages to the modem.
The system also activates the alarm circuit whenever the parameters exceed the normal conditions.
