For our project, We designed a system to be used in an ambulance that is capable of measuring patient vitals, including ECG, heart rate, and oxygen level. The system obtains the data of these measuring devices to be processed and then shown on the system’s built-in display. This data will be transmitted wirelessly to the hospital website, allowing doctors to observe patient vitals to make the appropriate diagnosis. The system also includes indicators that show the battery levels and alert the user when it needs to be recharged. Some key technologies used are the ESP32 microcontroller which is the component that links all of our other devices together. The MAX30100 sensor which is the sensor that measures heart rate and blood oxygen using infrared lighting. Finally we got an AD8232 ECG sensor which measures and displays ecg graphs by measuring the electrical activity of the heart. A notable accomplishment was getting the heart rate and blood oxygen to display on our display. The main thing we struggled the most with is transmitting the data. It was a lot more complex and challenging than we initially thought.
