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!

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) !

Question 6 months ago

Does anyone know what the LM393's are? Or the two little blue things with the hole in them? I'm knew to Arduino so some explanation would be greatly appreciated.

Great build! I really enjoyed putting it together. I will like to make the custom Proto-Shield but the link to the instructions appears to be broken. Are they still available?

add an I2C LCD to I2C pins, include the proper library, create lcd object and use 'lcd.print'

Question 1 year ago on Step 1

Hello,

How are you doing???

Has ANYONE installed an LCD, or thought about installing a mini-LCD to this project?

If so, PLEASE contact me.

Let me know.

I look forward to hearing from you..

attach PIR sensor to free digital pin and read the status. Attach a bluetooth module to the Serial port and use a bluetoot terminal app on your phone to read the data.
There already is a DHT11 sensor

add a wifi card. or better yet, ditch the ArduinoUNO and use an ESP8266

where we will be getting output results? on laptop or we need any lcd display?

what to do if we don't want pressure sensor in circuit?

There is a pressure sensor in the circuit: the BMP180.
Judging from the program the output is sent to the console

BTW, you can create pretty cool little online dashboard with these sensors. I just combined it with few other sensors and wifi cc3000 shield and you can get something on the pic bellow.

I have 10 more sensors to add to it. I am not really building weather station...more like replica of Mars Rover...so it is robot which has all these sensors to measure enviroment.
