Use Cases

Track and destroy

In this project we installed Polar inside our personal computer, to make sure that in case of theft we could easily track it down and destroy every sensible data we left inside. See the whole project here!

Zero motorcycles tracker

We love our electric bikes, and we are not satisfied with traditional trackers. With Polar we have a battery backup for stand-by power, a localization system and a direct connection to diagnostics, all in one small device!

Pet finder

With Polar it’s impossible to lose your lovely pet! You can 3D print a proper enclosure and fit it on the collar; Polar is very small.

What’s Inside?

Polar includes the following components:

  • ESP32 nano Wi-Fi chip
  • SIM7000 LTE Module
  • MPU6050 accelerometer
