ProtoCentral HealthyPi HAT for Raspberry Pi

Healthy Pi Hat

This HAT for Raspberry Pi 3 / 2 includes vital patient monitoring including ECG, respiration, pulse oximetry and features options to add blood pressure and body temperature sensing.

This is a one-of-a-kind, all-in-one HAT for your Raspberry Pi 2 /3 computer. Just plug it into the Raspberry Pi, install the graphical visualisation software and start using. Unlike available shields and breakouts that we carry for Arduino, this board combines all the functions into a a single board.

Repository Contents

Getting Started (On Raspberry Pi):

Mount ProtoCentral's Healthy PI Hat carefully onto the Raspberry Pi Board's GPIO Pins. And connect this setup with the Raspberry Pi's Display or HDMI Monitor. The Hat communicate with Raspberry Pi using UART interface. Connect the ECG electrodes and SPO2 Probe to the ProtoCentral's Healthy PI Hat.

It's now easy to get started with our brand-new installation script. Just follow the following steps on your Raspberry Pi.

To start, open up the terminal window (Menu -> Accessories -> Terminal) on Raspbian running on your Raspberry Pi:

Open the terminal

In the terminal window, type the following lines. 

curl -sS http://pi.protocentral.com/pi.sh | sudo bash

It really is as simple as that !!

This code will install all the required overlays, configuration and application files to get the Healthy Pi up and running.

After the script reboots, you should be able to see the GUI display on the screen

GUI in Processing

This completes the install!

If the above script does not work for you and would like to do a manual installation or would like to customize the code, check out [Advanced HealthyPi] (/docs/advanced-healthypi.md).

Using the HealthyPi GUI on Windows, MacOS and Linux

The HealthyPi board now streams the same data on the on-board USB port. This allows you to get the same data that goes to the Raspberry Pi, now on your desktop PC as well.

Java 8 is required on all platforms for running the processing-based GUI application. You can download Java for your platform from the following link.

Installing drivers (only for Windows)

HealthyPi uses the same drivers as an Arduino Zero. Once plugged in to the USB port, the device would be recognized as an "Unknown Device". You can locate the device is the Windows Device Manager and manually install the drivers provided in the "drivers" folder in the Windows Executable ZIP archive provided.

MacOS and Linux do not need any drivers to be installed.

Processing GUI Installation

Download the zip file containing the executable files from the following links for 32-bit/64-bit Windows. If you do not know if you have a 64-bit or 32-bit computer, please download the 32-bit version.

Simply download the appropriate file for your operating system, unzip the contents and run the executable program contained in it.

Programming the on-board SAMD21 microcontroller

HealthyPi now supports programming using Arduino !

If you wish to program your own code on the HealthyPi board, check out Modifying and recompiling HealthyPi Firmware.

Connecting the ECG Electrodes

A 3-electrode cable along with a standard stereo jack is provided along with the shield to connect the electrodes to the board. The other side of the electrode connector would connect to snap-on electrodes attached to the body. For testing purposes, you can use an ECG simulator to provide inputs to the board.

Warning: When connecting the electodes to the body, it is safer to disconnect the mains power source to the Arduino. For example, if you are using the Arduino along with a laptop, disconnecting the battery charger from the laptop would be a safe option.
