This is the code that runs on the Thing Plus - ESP32-S2 WROOM and is used to gather the data powering Doogledoor (code here, website here).
The logic is all in dooglebot.ino where we:
- Connect to the 2.4GHz band of the WiFi network at my house
- Watch for the digital signal from the OpenPIR module that's monitoring motion to toggle from low to high
- Send a POST request to the Flask application hosting the web interface on Cloud Run (with a healthy timeout set to allow for the Cloud Run instance to boot up in the likely event that it's shut itself down)
All of the parts for this project are:
- Thing Plus - ESP32-S2 WROOM
- OpenPIR motion sensor
- Waterproof enclosure
- USB A to USB C adapter + charger
All of this is sitting right outside the dog door to the backyard. To read more, check out the About page on Doogledoor.
Note: If you are viewing this project for inspiration, many of the sensitive credentials (wifi name, password, the REST endpoint and access token for the application, etc) are held in a header file - Sensitive.h - that is ignored from version control. You'll need to recreate this file locally yourself.
