Connecting-Raspberry-Pi-with-Firebase-Database-Using-Python

The following project was developed to collect the humidity and the temperature using the DHT22 sensor and Raspberry Pi v3 and store these data on the Firebase database.

The following instructions should work with any types of projects, since the basic idea has pretty much the same logic.

My project setup:

1. Raspberry Pi v3 model B, running Raspbian 4.9.35-v7.
2. DHT22 sensor with 3 pins: GND, 5V and Data.

First, you must configure your Raspberry Pi with the following:

1. sudo apt-get update
2. sudo apt-get install python-dev
3. wget https://bootstrap.pypa.io/get-pip.py
4. sudo python get-pip OR sudo apt-get install python-pip (new Raspian versions)
5. sudo pip install pyrebase

Note that you may need to update your pyasn modules (pip install --upgrade pyasn1-modules)

6. I also had to download some files for the DHT22 sensor from github: https://github.com/adafruit/Adafruit_Python_DHT

If you are done with the previous steps, you are now ready to start writing the python script. Take a look at the following link for the pyrebase: https://github.com/thisbejim/Pyrebase.

# This code should be used with every script that you will be using to connect to the Firebase database.
import pyrebase
from firebase import firebase
config = {
  # You can get all these info from the firebase website. It's associated with your account.
  "apiKey": "apiKey",
  "authDomain": "projectId.firebaseapp.com",
  "databaseURL": "https://databaseName.firebaseio.com",
  "storageBucket": "projectId.appspot.com"
}

firebase = pyrebase.initialize_app(config)

Look at the Pyrebase https://github.com/thisbejim/Pyrebase to look at the functions and how to use them.
