Build an Arduino Weather Station






This post 'Arduino Wather Station' was published in instructables.com


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: List of Material

  • Arduino, e.g. Arduino Uno Rev3
  • DHT11 Humidity and temperature sensor
  • BMP185 Barometer
  • Rain Drop sensor module
  • Soil Humidity sensor module
  • Breadboard or Custom ProtoShield
    Jumper Wire
  • Enclosure of your choice

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.
