Health Care
System

and Manuele Rusci
The Health care System is a device that can measure
the body temperature and the heart pulse frequency of the user. The real time
measured values are displayed in the LCD Display. The device is configured to
be connected to a PC to allow an off-line analysis of the data. The temperature
is measured by using a LM35 sensor that permits precision measurement. The
heart pulse frequency is measured by using a LED and a LDR putted over the
finger. This function can be improved since the results are highly variable.
Anyway in this project is demonstrated that it’s possible to measure the heart
pulse by using a LDR and a LED. The device is provided also with a serial port
to communicate the data to the computer. No PC software is developed yet but a
simple one can be interfaced with this device. The communication functionality
can be tested with a testing software.
