A rechargeable portable weather station, to view the basic weather details such as Temperature, Humidity and Pressure of the place your currently are at.

1

Features

  • Rechargable - It is a rechargable device, so no need to worry about batteries.
  • Light weight - Easy to carry and move around.
  • Small size - Can be easily placed at any place.

Why I built this

It is mostly for the people who are alergic to small changes in Temperature / Pressure, so they could find a perfect spot at the vacation to live at.

What new things I learnt

  • I learnt how a DS3231 RTC clock works and to read time using it and display it on the microcontroller.
  • I also got to know about BME280 sensor and it's working with microcontroller to collect weather related data.
