Lab 2 3010 Heart Rate Monitor
3010 Heart Rate Monitor
This lab uses a Max3010 and arduino to record heart rate and other
information to an arduino and display it on an external display.
Arduino, Max3010, LCD< OLED< 10k ohm resistor, 10k ohm potentiometer, Eagle
First the 3010 was wired and the example programs were run to make sure everything worked as seen below in Figure 1.
Figure 1. SRed Lights, IR, and G readings from Max 3010
readings were then plotted in the serial plotter to test the modules
ability to detect when something was in front of it as seen below in
Figure 2. Serial Plotter of IR and Red values.
was then calculated using the change in IR values and SPO2 was
calculated using the ratio of red to IR light as seen below in Figure 3.
Figure 3. SPo2 and Heart Rate readings
These values were then displayed on an LCD display as seen below in Figure 4.
Figure 4. LCD HR and OXY SAT display
OLED display was then wired into the sytem and a program was written to
display a real time pulse graph along with the HR and OXY SAT numbers
as seen below in Figure 5.
An Arduino Nano was used to replace the Arduino Uno to make the system cheaper and more compact.
Task 4: here
The PCB was created in Eagle. The schematic and PCB layout can be seen below
A whale was modeled to house the entire PCB and can be seen below
The whale was printed sucesffuly and will be assembeled when the PCBs arive.
