Maxrefdes117#: heart-rate and pulse-oximetry monitor

How to integrate this heart rate monitor with Raspberry pi or Arduino?

Hi @saishruthi10,

Maxrefdes117 sensor can be interfaced through the I2C protocol.

Since it’s I2C you can just:

  • Straight connect it to the appropriate pins that are on the RaspberryPi.

  • Buy a Grove connector and solder the VCC, GND, SDA and SCL to the appropriate pins and then you can connect it to the GoPiGo, GoPiGo3 & to the GrovePi. It’s important to connect the sensor to the I2C port.

Also, you need to develop a library for it that’s going to go on the RaspberryPi.
Here are a couple of useful links:

Pay attention, that if you want to make it work on your Raspberry Pi, you have to port the Arduino library. That’s because there’s no concrete documentation on how to access the resources on this sensor.
If you just want to use it on your Arduino, then just copy paste that Github project and you’re good to go.

Hope this helps you on your project!

Thank you!
