Science Faire

This is our motion to build an auto-irrigating system

[urbagri-blog]

function httpGetAsync(theUrl)            {                var xmlHttp = new XMLHttpRequest();                xmlHttp.onreadystatechange = function() {                    if (xmlHttp.readyState == 4 && xmlHttp.status == 200)                        console.log(xmlHttp.responseText);                };                xmlHttp.open("GET", theUrl, true); // true for asynchronous                xmlHttp.send(null);            }

       $("form").submit(function(e){            if(document.getElementById('chkbox').checked) {                console.log("irrigate on");                $(".notify").html("Irrigation is on");                httpGetAsync("irrigate_on.php")            } else {                console.log("irrigate off");                $(".notify").html("Irrigation is off");                httpGetAsync("irrigate_off.php")            }            e.preventDefault();        });

This is the base of the code. I will run the code for irrigation using the PHP file

This is how the web interface to the raspberry pi will look like. I have not integrated the sensors yet but the functionality is there. Code is in the next post

Initial Code for the program

#!/usr/bin/python from pubnub import Pubnub import sys from time import sleep pubnub = Pubnub(publish_key=<<key>>, subscribe_key=<<key>>) # Publish a welcome message def callback(message):    print(message) def publish(most, humd): pubnub.publish('moisture', {"moisture": most, "humidity": humd}, callback=callback, error=callback) publish(sys.argv[1], sys.argv[2])

This is the initial code to publish to the dashboard. The sensor reading will come next

This is how the dashboard will look. We will add more things but this is the jist of it. Coding is coming in the next post!

First day of Science Faire

This is actually the first day of our Science Faire. We started off by making a cost sheet and writing some code. I will post them in the upcoming posts. As of now, we have started our blog and we are ready to WIN!
