Creation
+ pin on DHT22 to VCC on ESP
out pin on DHT22 to GPIO pin 15 on ESP(can change depending on code)
- pin on DHT22 to GND on ESP
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
Once you have finished all the previous steps, hit continue on the applet page
