W5 - 13 (24/03/2013)

Design, construct and testing the sensor circuit (FYP2)

Objective :

Doing a lab session to test sensor circuit

1. to test the sensor range, sensitivity and capability. (in progress)
2. the input signal is amplified using the op-amp AD620 and another two op-amp OPA277
3. the output signal taken from each end of op-amp and dc coupler

Result : 

Still in progress: reason. needed motor and valve circuit, inflatable cuff, microcontroller circuit.

W4 - 13 (12/03/2013)

Design and Construct the circuit for BP monitor.


Objective : to build the full circuit system for Portable BP monitor. 



Result : [in progress] the circuit is separated by 3 parts : sensing, power supply and circuit controller (MCU).

Next Week :  Still on testing the sensor circuit
