BlueTrack Smart Treadmill Sensor

A low-cost sensor that makes any treadmill smart and will save you a lot of money as you don't need to invest in a high-end treadmill for virtual running.

All you need to do is buy your own hardware (microcontroller and sensor) for as cheap as you can find them on the market e.g. Amazon. Estimated total cost around 15 Euro.

The firmware can be installed directly onto the microcontroller and is completely free.
