Smart Life Challenge: GeoCar quick update On the line (online!)

camuyano

A few posts ago I plotted a map with the coordinates from the PSoC manually by creating a Google Docs Fusion table. Last night I finished a small script that post the data and a page to display the data.

The web part has three major components:

1. The web app (using Django, python)

2. The Rest Api (using Django rest framework, python )

3. Plotting the map (using Leaflet, javascript - using open street map data)

 

Oh and since it is in python you may run it anywhere, on your pc or on you Raspberry pi.

 

All code is on github, I commit as I go so it is not close to be organized but is on the line (online!).

Reads from PSoC into a text file

https://github.com/soynerdito/psoctracker/blob/master/test/import_bluetooth.py

Reads text file and sends it to the database

https://github.com/soynerdito/psoctracker/blob/master/test/gps_post.py

 

Here is a picture of the data I posted. In this example there are plenty of dots but all are close together because they were taken while I was programming with the GPS out the window. But you get the idea. Also for who didn't knew where Puerto Rico is, now you know. Boom!, extra info right there.

Note:

On another note, last night while I was sticking my hand with a CO sensor in the exhaust of the car it rained on me. I really enjoyed going outside with a laptop and a few cables for data gathering. It counts as an outside activity!

    A Rest API is like a new standard on how to access services on the web. For example Twitter has Rest API to provide others to use the service. It is like hitting a web URL with arguments. A rest service is more of a way of doing than a standard. For example if you use an ethernet network adapter on your microcontroller and receive data from a network client that can be called a rest API. Lets say your micocontroller is 192.168.1.2 and from a client you call http://192.168.1.2/L11 that can be called a rest service. On your microcontroller you may listen to the L11 string and do something, that can be like an instruction L > light 1 => light number 1 => ON. I don't know if it makes sense but that is the idea. Also a Rest API interface allow anything to connect to it. A simple micro controller can access the service not the case if I use something like a Web Service because that requires the messages to be pack into a binary package and that is restricted to smart clients like PCs.

    Django is a web framework that is coded in python. It is well because it is open source and well pack. Django and python allow me to put the app in a raspbery pi or a web hosting site. The PSoC by itself can collect data where a PC cannot go, but the data needs to be analized elsewhere and there is when I like others to join in. Right now, I use Django to create the database that holds the data collected from the PSoC.

    My project has a lot of ramifications because I see it as a solution not just a hardware solution. I like good DIY alternative for securing the vehicle. Since the PSoC is so small this will look pretty beautiful and small all packed in a small board.

  • Javier,

     

    Maybe a dumb question, but what is a 'Rest API'? I'm completely at a loss concerning Django, Rest API and leaflet. Although not really PSOC related it might be nice to show how you're using those frameworks / tools in your project. I've never done much in 'online' applications, so it would be interesting !!                  

  • Yeah,  but it doesn't count as exercise! image

     

    You might look at what Gelma did during the Energy Harvesting Contest for CO2 monitoring.
