How Can You Help?

The MAX30105 is a very powerful sensor but we’ve only scratched the surface of what it's capable of. If you are an algorithms guru and have a better method for calculating heart rate, or SPO2, or particle detection we would love to hear from you! Please send us a link to your repo, and we’ll include it here.
