Conventional telemedicine

systems using Public Switched

Telephone Network (PSTN)

land lines are already available

to enable a doctor to monitor a

patient remotely for home care

or emergency applications .

Program : Records the Blood Pressure of

patient and compare it with

normal range ,if it detects

abnormality sends it to doctor

or hospital

After completion of signals acquisition, the

microcontroller constructs

the SMS messages and

packs the data samples

in these messages to the

desired length, then communicates with the

mobile phone using at-

commands on its GSM

modem port to send the

message(s).

Heart beat sensor is designed to give

digital output of heat beat when a

finger is placed on it. When the heart

beat detector is working, the beat

LED flashes in unison with each heart

beat. This digital output can be

connected to microcontroller directly

to measure the Beats per Minute

(BPM) rate. It works on the principle

of light modulation by blood flow

(light detector & bright led)

GSM

Modem

You need only two wires (Tx, Rx)

except Power supply to interface

with microcontroller. Using this

modem, you can send SMS, data

and read SMS through simple AT

command .Inbuilt Powerful TCP/IP

protocol stack for internet data

transfer over GPRS. Input

Voltage: 9-12VDC [12]. GSM

made with third generation

POT (Patch Antenna on Top)

GPS module. The built in

3V3 to 5V level convertor

enable us to interface with

normal 5V Microcontrollers.

The 4 Pins are 5V, TX, RX,
