Biomedical Sensors

Breakout boards and kits for measuring signals from the human body: ECG and respiration, PPG and pulse oximetry, electrodermal activity (EDA/GSR), bio-impedance and body temperature. Most are designed in-house by Protocentral and released as open hardware, with schematics, layouts and Arduino libraries on GitHub.
Start with the ADS1292R ECG/respiration breakout or the MAX30001 ECG and bio-impedance board for biopotential work, the tinyGSR for skin conductance, or HealthyPi 5 for a complete multi-parameter vital-signs platform.
These boards are development tools for research, education and prototyping. They are not medical devices.
