This document describes a wireless telemedicine system that measures a patient's temperature and heartbeat using sensors. The system has two modules: a transmitter section placed with the patient that senses their vital signs and sends the data via ZigBee; and a receiver section in the doctor's office that receives the patient data and displays it on a PC for the doctor to monitor remotely. The system aims to make vital sign monitoring more affordable and accessible for patients compared to visiting hospitals or labs.

WIRELESS TELEMEDIA SYSTEM BASED ON ARM AND WEB SERVER
ABSTRACT:
Nowadays most of the humans have habits like smoking, drinking etc. This may
lead them in to severe health problems. So there is a need for everyone to
check up his or her body condition periodically. But hospitals are not much
equipped with this facility that leads them to go for other laboratories. People
won’t be able to afford the expenditure, as well as there is lots of time
consumption.
We have developed a system that goes a step further than the previous
approaches, being designed to measure temperature and heartbeat carried
by the patient.
Nowadays most of the humans have habits like smoking,
drinking etc. This may lead them in to severe health problems. So there is a
need for everyone to check up his or her body condition periodically. But
hospitals are not much equipped with this facility that leads them to go for
other laboratories. People won’t be able to afford the expenditure, as well as
there is lots of time consumption.

Transmitter section:
This section is placed with the patient’s. This module is also called as primary
section. The module hardware design is consists of the power supply, micro
controller , heart beat sensor and transmitter.
Here the purpose of the heart beat sensor to sense the heart
beat i.e. pulse rate and also blood pressure of a patient’s to be monitor. The
sensor sends the sensed signal to the amplifier circuit. The output signal of the
sensor is supposed to be amplified, because the output of the sensor in mill
volts signals. This signal cannot be sending to the micro controller, so through
the amplifier circuit the signal is boosted (or) amplified & given has an input to
the micro controller.
Temperature sensor used here is the thermistor. The purpose of using two
sensors, one is for the respiratory temperature and other to the body
temperature. The respiratory sensor is placed at the patient noise to sense the
respiratory temperature and the other sensor is placed anywhere in the body to
measure the body temperature. These sensors send the sensed signal to the
micro controller. The micro controller sends the entire signal to the secondary
section through the transmitter. This acts an input to the secondary section.
Receiver section:
This section is placed with the doctor consulting room. This module is also called
with a name secondary section. It consists of receiver, PWM transmitter and RS
232 interface with PC. Once the signal received from the transmitter of the
primary section to the receiver of the secondary section, it sends the signal to

the PC via RS 232. When the PC receives the signal, it display the history of the
patient i.e. we can monitor ECG signal, temperature, heartbeat and blood
pressure carried by the patient.
Finally the doctor monitors the entire history of the patient from the consulting
room itself and while monitoring the condition of the patient, the condition
goes abnormal it also viewed in
the PC.
By implementing this thesis of the project its safe the patient from the
danger.
