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.
