This Weather Station is a compact weather station that consists of several meteorological sensors that measure most of the useful weather 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 )

10. Air Quality Sensor ( PMS5003)

Apart from the Weather Sensors, I have added an additional port for the Soil Temperature and Humidity sensor, which is useful for agriculture.

I have also added some spare I2C ports to connect sensors as per the user's preference.

ESD Protection:

As the wind and Rain sensors are exposed to the environment, an ESD protection diode ( U7 ) is used to protect the board from unwanted voltage surges.

Complete Shutdown of all the sensors:

I have added a power switch similar to the LoRa module for a complete shutdown of all the sensors. It will reduce power consumption significantly.
