ESP32___DHT22___IFTTT_306268167_427924746149632_7414040424516888266_n.jpg Creation
You will need a Python IDE such as Thonny for this project. You can use any IDE, but for this project, we are using Thonny. To install and use Thonny:
This is how your circuit should look like. You will need the ESP32 microcontroller, DHT22 temp/humidity module, breadboard and jumper wires.
Go to https://ifttt.com/join
Sign up and create an account using the appropriate options
Once you are on "choose a service", type in Webhooks in the search bar and click Webhooks
- If you already have a webhooks account, skip this step
Otherwise, click the connect button and follow the steps on their website to create a webhooks account
Name the event for the trigger esp32 (it is case sensitive so be careful)
Select all the values you want returned to the spreadsheet, along with the path the sheet has to follow in your drive.
For this project, we are returning Temperature and Humidity values from the DHT22, so we will select Value1 and Value2
Once you have finished all the previous steps, hit continue on the applet page
Once you get onto this page, copy the api key and URL to paste into the code in Thonny
