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

high gain GPS Receiver (5V
Serial) with 4pin. Receiver is
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,
and GND
