kandi X-RAY | bangu Summary
This project is about smart ehouse which base on python, I use Raspberry pi to get senor data and GPIO to display message . Also it can be simply displayed on screen through a website which is based on Django. You can contact me via email: 564326047@qq.com(wangqingbaidu). Or visit my blog www.wangqingbaidu.cn for latest news. Later I will display all the mother board and sensors which I have already used. This will help anyone who wants to implement by their own.

2) I need to get the Arrays of numbers from each mall so I can insert into a ".push ()" function in google maps api and create the lat and lng for each polygon.
I'll explain how my firebase architecture will look:
I have several "Shopping Center Administrators", which in this JSON they call themselves (Aliansce, New Company).

Install bangu
You can use bangu like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
