• Pi Camera (Developed with a Pi Zero camera with relevent adapter)
• Temperature sensor (Developed with DS18B20+ One Wire Digital Temperature Sensor)
• Jump cables

Dependencies

python3 -m pip install -r requirements.txt
sudo apt install libatlas-base-dev libjasper-dev libqtgui4 libqt4-test python3-pyqt5 python3-opencv

install

git clone https://github.com/schizoid90/baby-monitor.git

Edit the monitor.service file to point to where you've downloaded the script to

ExecStart=/usr/bin/python3 {/path/to/your/script}

Move the file into place (systemd)

sudo mv monitor.service /etc/systemd/system/monitor.service
sudo chown root:root /etc/systemd/system/monitor.service
sudo chmod +x /etc/systemd/system/monitor.service

Then you should be able to start the monitor application with systemd

sudo systemctl daemon-reload
sudo systemctl enable monitor.service
sudo systemctl start monitor.service

Usage

• start

export TELE_APIKEY={{your_API_KEY}}
python3 telegram.py

This will start a connection to your telegram bot and start listening for commands

type /help in your chat screen to see a list of commands

Video

Video streaming is served via flask and shows a stream of jpg images on port 5000

Start by sending /video and stop with /stopvideo. It is also possible to send a POST request to the flask server running on port 5000

curl -X POST http://192.168.0.150:5000/shutdown

Picture

You can instruct the Pi to take a pciture and send it to that chat with /picture. This will also delete the picture sending so there's no need to worry about storage.
