A multiwavelength photoplethysmography dataset with blood pressure and heart rate reference measurements.

We present a dataset of photoplethysmographic (PPG) signals acquired from 127 seated subjects under controlled conditions. The signals were recorded using the MAX86150EVSYS, a commercial multiwavelength optical sensor capable of simultaneous acquisition at red and infrared wavelengths. Each signal was sampled at 100 Hz, following a standardized protocol that was formally reviewed and approved by the institutional ethics committee of Ospedali Riuniti di Foggia for biomedical data collection. In addition to the PPG waveforms, reference values of systolic and diastolic blood pressure, as well as heart rate, were obtained using a commercial sphygmomanometer. All measurements were performed while minimizing motion to ensure high-quality signals suitable for physiological modeling and algorithm development. This dataset is intended to support research in blood pressure estimation, PPG signal analysis, and the development of robust cardiovascular monitoring techniques for wearable health technologies. All data were collected with informed consent and in accordance with institutional ethical guidelines.
