The Pulse sensor board from ProtoCentral is our new addition to our open medical hardware line-up. Maxim's MAX30100 is a great new product that combines everything required for a pulse oximeter (including the LEDs and Photodiode !!) on a single tiny chip.

Measuring 14 mm wide and 40 mm long, this board is easily wearable on the finger to measure the pulse of blood. We even provide a Velcro strap to hold it.

Important Note: This device is only meant to be used for Research purposes and is NOT to be used as a medical device. This product is not FDA, CE or FCC approved for consumer use. 


  • Integrates a complete pulse oximeter including the optics. No need for a separate probe. 
  • Easy-to-use I2C interface to connect to any host microcontroller
  • Arduino library available
