Chicken Coop python app running on Raspberry PI.
Supports:
- capturing temperature using DHT22
- controlling actuator relay for opening/closing door
- streaming mjpg video using official camera module
- streaming audio using USB sound card using external icecast+darkice services
- controlling IR illuminator relay for night vision
- reading input button, if you want to open/close door manually on-site without a smart phone
- support for scheduled door opening and closing on sunrise and sunset
- stores the current state into config file so the door remain in position in case of power shortage
The app is split in two parts:
- the backend controls the GPIOs (relays, temperature readings, button)
- the frontend serves a website and captures video from the camera
Install dependencies:
sudo apt install python3-libgpiod # also installs libgpiod2
pip install adafruit-circuitpython-dht astralRun backend with
cd backend
python chickencoop_backend.pyRun frontend with
cd backend
python chickencoop_frontend.pyVisit http://your-raspberry-address:8080.
You can register chickencoop to start when raspberry turns on. Put those in
/etc/systemd/system/chickencoop_{frontend,backend} respectively.
