- Today, I'm going to talk about the Vernier Go Wireless Heart Rate.
When you order the Go Wireless Heart Rate, you'll get a pair of hand grips
along with a Polar Bluetooth module. What's nice is that this Polar Bluetooth
module can be disconnected and connected to an optional accessory of an extra size
chest strap. It just snaps right on and then the students can put this around
their chest and monitor the heart rate as say they're running around the track. It's
easily disconnectable as well and what's nice about these Bluetooth modules is each
one has a unique identifier number on the module itself, to help you identify which
module is connected to the hand grips you're using. So in order to collect
data, first I want to make sure my module is connected to the hand grips. Then I
want to take my Go Wireless Heart Rate and hold it in my hands in order to turn it on
I want to make sure that the metal part is towards the palm of my hands and
make sure that I'm holding on to it because this is how the sensor actually
turns on. So now that I am holding on to the sensor, I'm now going to connect it to
Graphical Analysis. First, I select "Create an experiment", then I'm going to
select my source which is going to be my "Wireless sensors" and I am going to
connect to the module number that is connected to my hand grips.
So once it's connected, you can see I actually
get a live readout over here that showing on my graph
and that's nice because it shows me that I am actually connected to the Go
Wireless Heart Rate. So now, we're ready to collect data.
I'm going to press on "Collect" and I'm going to collect data for about 15 to 30
seconds at a resting rate in order to get a baseline to compare to any sort of
cardiovascular activity I do. So now, it's been about 15 seconds. So I'm going to go
ahead and start running in place to elevate my heart rate.
So now that I've been doing this for about 60 seconds, I'm going to stop and
I'm going to monitor my heart rate and watch it go back down to my resting heart
rate that I started at.
Now that my resting heart rate has stabilized, I'm
going to go ahead and press "Stop", and now I have my data for my first run.
What's nice is that once I let go of the grips, they will actually turn off and
disconnect, saving some of the battery life on our Go Wireless Heart Rate.
The other nice thing is I can go to the experiments now and my experiment has
automatically been saved in Graphical Analysis so you don't have to worry about
losing any of your data. For any questions you have about this sensor
or any of our others, please visit our website.
