This Weather Station is such compact weather station that consists of several meteorological sensors that measure the following parameters:

1. Internal Temperature (BME280)

2.Humidity (BME280)

3. Barometric Pressure (BME280)

4.External Temperature (DS18B20)

5. Wind Speed ( Sparkfun Weather Meter )

6. Wind Direction ( Sparkfun Weather Meter )

7. Rain Gauge ( Sparkfun Weather Meter )

8. UV Index ( SI1145)

9. Lux Level ( BH1750 )

I have designed a customized PCB for this project. It is designed in such a way that you can conveniently integrate different combinations of sensors according to your actual application needs.


Why a Weather Station?

Imagine you are residing at a place that is far away from the meteorological department. In such a case, the weather predictions you get may not be the most precise. This is where home weather stations become more advantageous. This small weather station can provide accurate data regarding the weather parameters of where you live.

Today, data on localized weather, known as microclimates, is the new frontier for more precise and accurate weather forecasting. As a result, the collection of weather data is becoming increasingly smaller and gridded.


Applications:

The applications of this type of small portable weather station are vast in the area of smart agriculture, smart city, solar power plants, construction site, etc.
