Polar A1 Heart Rate Monitor
MCU
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
  Atmels Integrated Development Environment (IDE).

11
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

12
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.
