HealthyPi v4 – Unplugged, monitors vital signs using ESP32
https://www.electronics-lab.com/healthypi-v4-unplugged-monitors-vital-signs-using-esp32/
HealthyPi v4 is a wireless, wearable, open source vital signs monitor powered by ESP32. Reliable health monitoring has traditionally required that we tether ourselves to machines capable of recording our vital signs around the clock. Outside of a clinical setting, however, this is rarely practical. We developed HealthyPi v4 in part to address this challenge. […]
