Final System
The total system together. Unseen are the sensor and arduino board. There was no casing designed for this project.
Analog Design
Analog Circuit Designed by Analog Team. The team had 2 weeks to design a board to fit all the filters, amplifiers, and signal connections together.
Analog PCB
Final analog circuit board. This is a handmade PCB from the above design.
Analog Signal
The signal received from the sensor, after analog processing, to the oscilloscope. This was used to tune the digital thresholding.
System Display
Sample readout of heart, with high Pressure alarm. The device also includes a buzzer to indicate heart beat (during the QRS-complex).
