Internet of Things Project - Smart Grocery

Steps to take:

1. Setup 2 Raspberry Pi according to the fritzing diagrams below

2. In the above Raspberry Pi, there is another hx711 sensor. It can be patched by: VCC pin to 5V, GND pin to GND, DT pin to GPIO5 and SCK pin to GPIO6.

3. On both Raspberry Pi, add the following into the file "requirements.txt":

• Asgiref
• autopep8
• django==2.2.10
• pycodestyle
• pytz
• sqlparse
• Unipath
• dj-database-url
• python-decouple
• gunicorn
• whitenoise
• boto3
• simplejson
• requests

4. Save the file and execute "pip3 install -r requirements.txt"
5. Execute "sudo raspi-config". Go to interface setttings and inteface options -> enable Serial User need to check what interface the barcode is on. it might be on /dev/hidraw0 or /dev/hidraw1 or in some cases /dev/hidraw2 . User need to then go to line 118 of api.py and edit accordingly.
6. On the 1st Raspberry Pi, Open Arduino IDE and upload "capture_light.ino"
7. Execute the following files in different terminals on the 1st Raspberry Pi: weight.py, LDR.py, picam_rekognition.py
8. Execute the following on the 2nd Raspberry Pi: “python manage.py makemigrations” and “python manage.py migrate”
9. On the 2nd Raspberry Pi, execute “python manage.py runserver” to start the web application. To specify port number, add 0.0.0.0:<port_no> at the end.
10. Execute "telegram_app.py" for Telegram Bot.
