The gator:particle is an amazing tool that uses a high-sensitivity pulse oximeter and heart-rate sensor, the MAX30102. Similar to the SparkFun Particle Sensor, with the MAX30105 high-sensitivity optical sensor, the gator:particle can also be used for particle detection. The primary difference between these boards is that the SparkFun Particle Sensor also uses a green LED that requires more power than the micro:bit can provide. This tutorial will show you how to get started using the gator:particle sensor with the gator:bit (v2) in the micro:bit development environment.

Required Materials

To get started, you'll need a micro:bit to control everything. Each of the products below includes a micro:bit, but the kit and bundle also include some additional accessories that you may want as well.
