+ 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
