The aim of my research is to recover the waveform of a human heartbeat using an IMU, I am currently at the stage of data acquisition and preliminary signal processing, I want to assess the quality of the data acquired with the IMU, so I need to have a ground-truth to compare it against, I currently own an ESP32 DEVKIT V1 MCU, an MPU6050 (IMU sensor), and I intend to buy either an ECG I have an ESP32 DEVKIT V1 MCU, an MPU6050 (IMU sensor), and plan to buy an ECG sensor or a PPG sensor (they are used as ground-truth), and note that I have to collect data from both sensors with perfectly synchronised time series, as this is the only way to have a meaningful comparison. How should I design the solution? Can I use one MCU to control both chips? Or do I need to use 2 MCUs?
