| + | ==== Concluzii ===== | ||
| + | Upon completion of this project, I developed a thorough comprehension of how a pulse oximeter operates. I actively utilized Arduino to write the required code and employed the `Serial.println` function to visualize the signal output on the serial monitor. Additionally, I utilized Fritzing to accurately construct the circuit diagram. Furthermore, I gained valuable knowledge on effectively filtering and amplifying biomedical signals using an operational amplifier and a high-pass filter. Moreover, I successfully implemented signal filtering directly within the program code. | ||
| - | ===== Concluzii ===== | + | Pulse oximeters play a crucial role in medical settings, given their non-invasive nature, affordability, and reasonably high level of accuracy. When measuring heart rate and oxygen saturation, it is advisable to use a pre-calibrated sensor, as each device possesses distinct parameters that can vary based on its specific design and construction. |
