HealthyPi 5 WiFi & BLE biosignal-acquisition sensor platform captures body temperature, ECG, PPG, SpO₂, and other vitals (Crowdfunding) - CNX Software
Summary
HealthyPi 5 is an open-source sensor platform for biosignal acquisition based on Raspberry Pi RP2040 microcontroller and ESP32-C3 WiFi & BLE module used to capture vitals such as electrocardiogram (ECG), respiration, photoplethysmography (PPG), oxygen saturation (SpO₂), and body-temperature data. While the HealthyPi 5 also follows the Raspberry Pi HAT form factor and can be connected to a Raspberry Pi SBC to analyze the data, it can also be used as a standalone device with the processing handled by the RP2040 dual-core Cortex-M0+ microcontroller and connectivity through an ESP32-C3 wireless module, and data visualized on a 3.5-inch SPI display or a smartphone over WiFi or Bluetooth. The EAGLE schematics and PCB layout for all PCBs, some Python scripts, and the JAR file for the desktop GUI can be found on GitHub. We’re told the source code for the desktop GUI and mobile app are on this repository, but at the time of writing, I could not find either. There are four main ways to use the HealthyPi 5 board: • As a standalone system with the carrier and 3.5-inch touchscreen display • As a standalone system transmitting the data to a mobile host (smartphone, tablet…) over WiFi or Bluetooth • As a Raspberry Pi HAT with the single board computer handling processing and display of the data • As a USB data logger connected to a laptop or other host The project has launched on Crowd Supply crowdfunding platform with a symbolic $1 funding target.
