Vernier Go Wireless® Heart Rate with LabQuest 2 - Tech Tips

Colleen McDaniel demonstrates the use of the Go Wireless® Heart Rate and LabQuest 2 to monitor heart rate before, during, and after exercise.

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 poly 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 reattaching 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 Poly module is connected. Then, I need to connect my LabQuest too 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 [00:02"00] that is connected to your hand grips. Then I'm going to select Ok, 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 a amount of recovery time. Now that we're done collecting data, we can now let go of our 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 [00:04:00] 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 Ok and you can see I'm now going to be reconnected and can no collect the next round of data.
