- Today, I'm going to talk about the Vernier Go Wireless Heart Rate.
When you order a Vernier Go Wireless Heart Rate,
you'll get a set of hand grips along with a Bluetooth
polar module that connects to that. What's nice is that the Bluetooth module can
actually be disconnected from the grips and then connected to either any other
hand grips or it can actually be connected to an accessory exercise heart rate strap
in which you just snap it on, and then students can place it around their chest
and can monitor their heart rate as, say they're running around a track.
So I can disconnect this Bluetooth by unsnapping it, and then can reattach it
directly back to our hand grips. What's important about this Bluetooth module is,
located on the top is a unique ID for every module. The unique identification
helps you pick which module you need to connect to when you're using it for data
collection. So in order to collect data, first I want to make sure that I connect
my module to my hand grips. Next, I want to make sure that I'm holding on my hand
grips and that the metal is touching my palms. Now, what's great about this device
is that the Go Wireless Heart Rate only turns on when it notes
a connection with the hand grips.
So in order to collect data, I'm going to make sure my polar module is connected.
Then I need to connect my LabQuest II to my Go Wireless Heart Rate. In order to do
that, first we're going to select Sensors, then Go Wireless Setup and then, once the
Bluetooth is enabled, you're going to select the module
that is connected to your hand grips. Then I'm going to select Okay, and after a few
seconds you will see that you get a live reading of the student's heart rate. This
is nice because this then shows you that the sensor is indeed connected to the
LabQuest. Now our duration is currently set at 600 seconds, I'm going to modify
this by tapping on Duration, I'm going to tap on it again, and I'm going to change
this to 200 seconds, and then tap Done, then tap Okay.
Now, we're going to start data collection.
So as data starts being collected, what we want is students to just stand still
for about 15 to 30 seconds to get what we consider baseline heart rate data. This
way, they have an idea of what they're at resting and can compare that to what they
are at activity. So now, I'm going to start running in place to simulate cardio
activity and cause my heart rate to go up.
Okay, after 60 seconds I'm going to stop running in place,
and we're going to keep collecting data so that we can watch how
long it takes to get back down to our resting heart rate,
giving us an amount of recovery time.
Now that we're done collecting data, we can now let go of the
hand grips and as soon as we let go of the hand grips it now turns them
off saving battery life.
Now if we wanted to reconnect and have
another student try this, we have to wait about 30 seconds after we've let go,
before we can reconnect and you'll be able to see that we can reconnect once it says
offline. Now that it says offline, I can then hold on to my hand grips again
because remember you have to hold on to them in order to turn them on. I'm going
to tap on the red box, tap on Go Wireless and then Connect. And now that I'm
connected it's going to pick up my module again, I'm going to select it,
select Okay and you can see I'm now going to be reconnected and can
now collect the next run of data.
