It's a minimalist satellite which is inspired by documentary films on robot rover which have landed on the moon for example.

The objective was to be inspired by this robotic design while creating an aesthetic object that could be placed wherever you want in your home.

The minimalist satellite gives you information like ambient temperature and humidity, but only if you get close to it :)

    Component Testing

    We have been testing the functionality of each component separately, advancing step by step to ensure that everything works independently. This approach helps us avoid situations where we cannot identify the source of a problem. To test the validity of each component, we used basic codes available in the component's library. For example, to check the humidity, we observed the results on the serial monitor.
