    In spite of the improvement of communication link and despite all progress in advanced communication technologies, there are still very few functioning commercial wireless monitoring systems, which are most off-line, and there are still a number of issues to deal with.

    Therefore, there is a strong need for investigating the possibility of design and implementation of an interactive real-time wireless communication system. In our project, a generic real-time wireless communication system was designed and developed for short and long term remote patient-monitoring applying wireless protocol. The primary function of this system is to monitor the temperature and Heart Beat of the Patient and the Data collected by the sensors are sent to the Microcontroller. The Microcontroller transmits the data over the air.

    At the receiving end a receiver is used to receive the data and it is decoded and fed to Microcontroller, which is then displayed over the LCD display. If there is a dangerous change in patient's status an alarm is also sounded.

    in the heart beat monitor of the circuit there is a hanging leg of a resistor...is it really not connected?...

    Yes its a variable Resistor, we use the one side leg and the center tap only.

    good day sir!!!i would like to ask about your
    biomedical monitoring system on how the system works when it comes to temperature...can the system directly monitor the temperature of a patient w/out any contact to his/her body...and what is the maximum range from transmitter to the receiver to successfully transmit and receive data...thank u in advanced...more power to you and god bless!!!

    No the system can get the body temperature if the sensor was not attached to the body of the patient
    The maximum distance of the TX/RX used in the circuit was 100meters at open air and it will be get reduced when we use it in buildings.

    Yes you can change it to send sms.
    This project works on RF commnunication.
