Abstract:
In real life, almost all the projects have strict requirements of time and cost. This
wireless health monitoring system was designed and implemented to achieve a
lower power, lower cost and reliable monitoring system that would accurately
measure the heart rate and temperature of the human body.
In this project, we have designed and developed a wireless communication system
for remote patient monitoring. This project is a zigbee based wireless health
monitoring system that is used to measure the patient’s body temperature and heart
rate. This is achieved by using a PIC microcontroller and interfacing it with a Heart
rate sensor circuit comprising of a LDR (Light dependent Resistor) and a LED
(Light Emitting Diode), and also a temperature sensor LM35 for the measurement
of the body temperature. The microcontroller then transmits the data over the air by
using Zigbee modules. At the receiving end, the receiver receives the data and
another microcontroller which sends the values to the PC which is then displayed
on the doctor’s Personal Computer or a Laptop with an easy to use graphical
interface. The software receives the data and interprets it as heart rate and
temperature and also alerts the doctor in case of an emergency. With the help of
this health monitoring system, the doctor or medical staff can access the data from
their office and examine it to ensure the health of the patient. This project has the
potential to offer a wide range of benefits to the medical personnel, patients and
society through continuous monitoring of the patients and providing early
detection of critical conditions. This wireless health monitoring system is easy to
use and provides accurate measurements.
