Story

Have you ever wondered about building an Arduino weather station on your own? Well, this might be your chance to build a basic IoT weather station. This will be an interesting project and I will be guiding you through this. In this project, you will be learning how to record measurements using the sensors and store them in Google Spreadsheets.

I got this idea after referring to Stephen Borsay's 'Transmit ESP8266 Data to Google sheets' project. Likewise, you can also upgrade this project by adding more sensors to measure weather conditions.

Hardware components used in this project

NodeMCU devkit V1.0

Coding

You can find the codes for this project by referring to the original project which is included as a hyperlink in the beginning.

You will be needing the PushingBox online service to act as a trigger to send the data from your NodeMCU microcontroller to the Google sheets.

Google sheet

You will be needing your gmail address to create a spreadsheet in google sheets.
Enter your column headings which will be Date, Humidity (%), Temperature (in °C), Temperature (in °F), Heat index (in °C), Heat index (in °C) and More Accurate Temperature (in °C).
Copy and save your spreadsheets URL key which will be found in the URL between "/d/" and "/edit".
Go to tools and click on 'Script Editor'.
The code which will be included in your Gscript is given in the original project. The only change in the codes will be to add another case for the more accurate temperature.
Save the script
Deploy as a web app. At first, Google will send you a warning saying that it is unauthorized but it's okay because you are the author.
Save the web app URL

PushingBox

Login with your gmail account
Create a new service by selecting 'CustomURL'
The root URL within the customURL configuration will be the web app URL saved in the previous step.
Select 'GET' method
Now, you must create a scenario using this service.
For 'GET' method, the statement begins with '?'
