Raspberry PI Zero W Camera and a simple http server with stream and some weather-data for outdoor bunnys (Edgar and Puffy):

Parts

• Board: RASP PI ZERO W Raspberry Pi Zero W (Reichelt)
• Camera: RPIZ CAM 5MP 170 Raspberry Pi Zero (Reichelt)
• Sensor: AM2302 / DH / DEBO DHT 22 WIRE (Reichelt)
• And also:
  • SD-Card for the raspberry
  • powersupply or powerbank
  • a cable with micro-usb for power to the raspberry

Build

Connect all the parts:

• Camera to the raspberry
• Sensor to the raspberry (black = any ground pin, red = any 3,3v pin, data = pin GPIO 4), see raspberry pi zero pinout
• Build a or use a nice housing for the componets. I used a cardboard and some hotglue for development and testing:

Install

1. Setup Raspberry PI Zero w with current raspian and login via ssh.

2. First, get updates:

   sudo apt-get update
   sudo apt-get upgrade
   sudo apt-get dist-update
   sudo apt-get autoremove
   sudo apt-get autoclean 
   

3. Reboot: sudo reboot

4. Open system settings with sudo raspi-config and change...

   • Enable camera
   • Change password
   • Set hostname
   • Set timezone
   • Set WLAN country
   • Expand filesystem

5. Reboot: sudo reboot

6. Install tools:

   sudo apt-get install fish mc git python-picamera python3-picamera python3-pip libgpiod2
   sudo pip3 install --upgrade setuptools
   pip3 install adafruit-circuitpython-dht 
   

7. Clone git repository https://github.com/haenno/bunnycam to home folder:

   cd ~
   git clone [e-mail]:haenno/bunnycam.git
   

   Maybe you need to first create new ssh key with ssh-keygen -t ed25519 -C "[e-mail]" and add it to your github account.

8. Setup bunnycam webserver and logging als systemd deamons:

   sudo cp /home/pi/bunnycam/bunnycamlog.service /etc/systemd/system
   sudo cp /home/pi/bunnycam/bunnycamwww.service /etc/systemd/system 
   sudo systemctl daemon-reload
   sudo systemctl enable bunnycamwww
   sudo systemctl enable bunnycamlog
   

9. Get crontab to grab updates...

   Open crontab with sudo crontab -e and insert 1 line:

   0 4 * * * date >> /var/log/bunnycamsys.log && vcgencmd measure_temp >>  /var/log/bunnycamsys.log  && apt-get update -yq >>  /var/log/bunnycamsys.log && apt-get upgrade -yq >>  /var/log/bunnycamsys.log  && apt-get dist-upgrade -yq >>  /var/log/bunnycamsys.log
   

   So it will check for system update every day at 04:00.

10. Try to open the stream: Open your browser and type http:// in the adressfield, followed by the hostname or ip of your raspberry and the port :8080. I my case the hostname was "bunnycam", so the url was: http://bunnycam:8080

Todo

• Build better caseing.
• Add WLAN antenna.
• Update pip3 with crontab.
• Self check if network / system is running. Reboot if not.
• Send logs / status via email.
• Save some of the images (for timelaps?).
• Add a led stripe and control via http.
