Preliminary Design

Sensors Model * DS 1620 Digital Temperature Sensor data MCU - accuracy of ± 0.5°C - range of -55 to 125 °C - digital interface included - $ 5.75

* Polar A1 Heart Rate Monitor * Polar A1 Heart Rate Monitor MCU 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 !! $59.99

The Microcontroller Model The microcontroller model will collect the sensory data and create a data package to be transmitted to the host computer. 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? Lasilky team chose AT86ZL3201 as the microcontroller chip. Why? The development kit for the desired microcontroller will be: STK500. 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 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). 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. 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. 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? ZigBee technology is used in the MCU, transmitting, and receiving chips. Why ZigBee? Lasilky team chose AT86RF210 as the transceiver chip. Why? Lasilky team chose AT86RF210 as the transceiver chip. Why? Antenna: ANT-2.45-CHP Antenna: ANT-2.45-CHP
