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!

Step 1: What You Need?

1 x Arduino Board ( Arduino UNO R3 used in this project tutorial.)
1 x DHT11 Temperature and Humidity Sensor
1 x BMP180 Barometric Pressure Sensor Module
2 x Rain Drop Sensor Module
1 x Soil Moisture Sensor Module
1 x Prototype Shield with Mini Breadboard or Custom ProtoShield
Female-to-Male Jumper Wires
Male-to-Male Jumper Wires

Optional
1 x Arduino Uno R3 Acrylic Transparent Casing
Cable Cover / Management

You can buy Arduino Compatible UNO Ultimate Starter Kit / Learning Kit at here.

Don't have components? Don't worry. Just click the component's name. 

Step 2: Build Your Circuit.

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 BMP180

• 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: Upload Code To Board.

Below is the Arduino Weather Station code. Include the library from AWS_library.rar, upload the code to your Arduino (Mine Arduino UNO R3), and you should have no problems.

Step 4: Test With Your Circuit. 

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) !
