This project was created on 02/12/2016 and last updated 3 years ago.

Description

This is a wireless, battery-powered physiological sensor that sends electrocardiography (ECG), galvanic skin response (GSR) (AKA electrodermal activity) and respiration (plethysmography) signals to a remote computer in real-time. The circuit uses instrumentation amplifiers, some basic analog filtering, digital acquisition with an Ardweeny (Atmega328P), wireless transmission with a NRF24L01+ chip. A GUI runs on Scilab to display the data and to compute heart & respiration rate.

Yes I know about the BITalino thing but I found it a bit expensive and it's more fun to design all the sensors from scratch. Plus it doesn't have a respiration sensor and I find that it's a valuable addition to a physiological analysis. Open source documentation for the hardware on such projects is almost inexistant so here is my contribution!

Hi! 

can you provide some more information on the respiration sensor? please :)

  Are you sure? yes | no

Hi sorry I've just seen your comment. What do you want to know? Basically it's a belt made with a section of conductive rubber cord, like this one : https://www.adafruit.com/product/519

  Are you sure? yes | no

Thank you for the link! I was not sure what kind of sensor you are using and if you are measuring the expansion of the chest, but now this is clear. Still searching for a sensor that is unnoticeable... ;)

  Are you sure? yes | no
