Engineering note. Values on this page are raw ADC counts and sensor readings before filtering. PPG shows 18-bit counts from the MAX30105 photodiode. ECG shows the AD8232 front-end output. IMU channels are in g (accelerometer) and deg/s (gyroscope). Temperature is in degrees Celsius. Use the /analysis page for clean cardiac waveforms and derived metrics.
