HealthyPi v4 is a HAT for the Raspberry Pi, as well as a standalone device that can measure human vital signs that are useful in medical diagnosis and treatment. HealthyPi v4 sets a new standard in open source health solutions with mobility, wireless and wearable capabilities. This device presents a snapshot of the user's medical condition within his/her environment and opens up medical research possibilities.
HealthyPi v4 measures the following parameters in real-time and with high accuracy:
- Electrocardiogram (ECG) data, heart rate, and heart-rate variability
- Respiration based on impedance pneumography
- Pulse oximetry (SPO₂)
- Body temperature
HealthyPi 4 is affordable and accessible and the open source aspect means that it’s easy to expand upon.
You can now purchase the HealthyPi v4 HAT Kit from Crowd Supply
