{{Tuto Step
|Step_Title=<translate>Install Thonny or Other Python IDLE</translate>
|Step_Content=<translate>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:

*Go to https://thonny.org/
*Download
*Install and then open</translate>

{{Tuto Step
|Step_Title=<translate>Setup Circuit</translate>
|Step_Content=<translate>This is how your circuit should look like. You will need the ESP32 microcontroller, DHT22 temp/humidity module, breadboard and jumper wires. 

* + 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</translate>
