Preliminary Design
Sensors Model
* DS 1620 Digital Temperature Sensor
- accuracy of ± 0.5°C
- range of -55 to 125 °C
- digital interface included
- $ 5.75
* Polar A1 Heart Rate Monitor
$59.99
•Heart rate comes from chest strap sensor / transmitter
•Signal is taken from the wrist receiver as a negative going pulse for each
heart beat
•Signal will be conditioned using Low Pass Filter to remove noise
•Average taken as frequency over three samples
There is a Problem !!
The Microcontroller Model
• The microcontroller model will collect the sensory data and
create a data package to be transmitted to the host computer.
• Lasilky team chose AT86ZL3201 as the microcontroller chip. Why?
• The development kit for the desired microcontroller will be:
STK500.
• The STK500 development kit gives an opportunity for designer to code
on AVR.
• The STK500 has features for testing new designs and developing prototypes. It
also supports Atmel’s Integrated Development Environment (IDE).
Wireless Communication Model
• The wireless communication model of Health Mate consists of
transmitting transceiver and a receiving transceiver.
• Transceiver at the wearable unit sends the encapsulated data
package processed by the MCU to the Atmel transceiver at the
base station.
• ZigBee technology is used in the MCU, transmitting, and
receiving chips. Why ZigBee?
• Lasilky team chose AT86RF210 as the transceiver chip. Why?
• Antenna: ANT-2.45-CHP
Graphical User Interface (GUI)
Why Java?
• Java is object oriented language .
• Java is independent of the host platform.
• Java is considered being a higher-level
language than similar languages such as C
and C++.
• Java contains language facilities and large
libraries for different network systems.
• Java is available in most of the engineering
laboratories .

Future Improvements
• Web Page using HTML can be easily
updated and uploaded whenever there
is new information.
-Patients will use health Mate at home
-accessible at any time.
-It will show the date and time of the updated process.
-feedback by nurses.
• Different sensors can be added to the
system, such as a shock sensor and a
blood pressure sensor.
