MAX3010x Pulse Oximeter Modules (Part 4)
The MAX3010x sensors can do more than just heart rate measurements. Let's do some pulse oximetry.
MAX3010x Pulse Oximeter Modules (Part 3)
Our previous approach for heart rate measurements didn't work very well. It's time for a better and more scientific algorithm.
MAX3010x Pulse Oximeter Modules (Part 2)
Now that we can acquire data with MAX3010x modules, it's time to apply our heart rate detection algorithm to it.
MAX3010x Pulse Oximeter Modules (Part 1)
It's time for some more advanced heart rate sensors. Today, we are going to take a look at the MAX3010x pulse oximeter sensor family.
Heart Rate Module (Part 3)
As promised, we are going to look at another solution for detecting heart beats. This time without using a buffer.
Heart Rate Module (Part 2)
In the last part of this tutorial, we already tried out the KY-039 module. Today, we are going to implement a proper heart rate detection.
Heart Rate Module (Part 1)
Today, we are going to look at a very simple heart rate sensor. Let's discover how it works and how we can measure the heart rate with it.
