Safe & Sound T-Shirt for Monitoring Elderly and Physically Challenged Patients #8 : Sugar, Spice and Everything Nice....

Hello guys,

 

How its going?

 

Here is this weeks write up, I just put up everything together image and placed them on my cycling t-shirt image.

I've made a change with the pulse sensor, I'm currently using a one based on MAX30100, though its an obsolete product I found it to be simple and also capable of giving SpO2 Level too.

 

Some soldering worksimage

Some more soldering.....

Skipping some soldering photos...

 

Well I connected the Pulse, Temperature, Light and Accelerometer to the I2C Bus, 3V3 and GND.

 

The ECG is connected to 3V3, GND, Analog Pin and 2 GPIO Pins.

The Breathe Sensor, Analog Pin, 3V3, GND

 

Here is the T-shirt

Placing the sensors into the T-shirt.

The code was written based on the Multitasking Event Library in Energia IDE and is available on Github.

Well the sugar, spice and everything nice turned out to be everything "noise".

 

A sample of ECG captured, still wondering what is causing out the noise.

Cheers,

    yes, it would be good to know the time between two noise peaks. then 1/x it and we know the frequency. that can be an indicator.

    How are you protecting your circuit and user from moisture? DAB

    still wondering what is causing out the noise It looks like it's the same period between peaks. Are you sure it's not the com port buffer, since you're driving the output at 115200 baud.

    For now we have very hot weather DAB so I'm not much worried, but have stuck some kepton beneath the sensors to protect from sweat, need to find some efficient way for it.
