WeatherStation

The main goal of the project is to create an autonomous Wi-Fi weather station based on STM32F103. ESP-01 is used for transmitt data to server and BME280 for getting temperature, humidity, pressure readings. In the future, this weather station will become part of the smart home.

Legs configuration for weather station

In the dark, the work of the station is provided by a 18650 lithium-ion battery, and in the light by the solar panel, which charges the battery and provides sleep power.
