Arduino Weather Station (AWS)




In this project, we will be making a weather station that measures air pressure, temperature, rain drop, soil humidity and air humidity using Arduino which save the data for data acquisition!

Arduino Weather Station (AWS)




It’s a fairly easy project and can be used either on its own or part of something bigger, check it out >> Integrated Weather Station (IWS).

Step 1: List of Material

For this project, we will be using:

– Arduino boards (mine Arduino Uno Rev3)

– DHT11 Humidity and temperature sensor cost: ~5.00 USD

– BMP185 Barometer sensor cost: ~6.00 USD

– Rain Drop sensor module cost:~2.00 USD

– Soil Humidity sensor module cost:~2.00 USD

– Breadboard or Custom ProtoShield (Check it out how to make it >> )

– Jumper Wire

Step 2: Hardware Connections

In general, the connections are very simple. Follow the instructions and images above, and you should have no problems.

Connecting Rain Drop Module

  • the VCC pin on Arduino’s 5V output
  • the GND pin to Arduino’s GND and
  • the Analog Data to Arduino’s analog pin 0

Connecting Soil Humidity Module

  • the VCC pin on Arduino’s 5V output
  • the GND pin to Arduino’s GND and
  • the Analog Data to Arduino’s analog pin 1

Connecting BMP185

  • the VCC pin on Arduino’s 3.3V output
  • the GND pin to Arduino’s GND
  • the SDA (Serial Data Line) pin to Arduino’s analog pin 4 and
  • the SCL (Serial Clock Line) pin to Arduino’s analog pin 5

Connecting DHT11

  • the VCC pin on Arduino’s 5V output
  • the GND pin to Arduino’s GND and
  • the DATA pin to Arduino’s digital pin 4

Step 3: Arduino Programming

Below is the Arduino Weather Station code. Include the library from AWS_library.rar, upload the code to your Arduino (Mine Arduino Uno Rev3), and you should have no problems.

You can clone and edit the code in any way you prefer.

Step 4: Enjoy!

Power through batteries or a plug and you’re good to go.

After making sure that everything works smoothly, you can take this project into bigger project. Check it out >> Integrated Weather Station(IWS) !
