How to upload data to website SQL database directly from Pro2 PLUS - Palmyweather - 20-05-2018

Using WeatherDuino Pro2+ to upload data to a website database with SQL

(Available in Receiver Software Release v6.x onwards)

A Brief “How To” Guide. Please note that this is not a “one for all” guide, settings may be different depending on your server.

Step 1: Set up the database on the web server

Log into your website’s control panel.
Navigate to “MySQL® Databases” on your server.
Create a new database if you have not already got one you would like to add to.
Navigate to “MySQL® Users”, usually found as part of the “MySQL® Databases” settings.
Create a new user if you do not already have one set up.
- Create a user name
- Create a password
- Select the database you would like that new user to be associated with.

Step 2: Enable remote control (This step may not be required)
For security, by default the web server will be protecting itself from remote unauthorised access which could modify or damage the data. Permission may need to be granted to allow your IP address assigned by your internet provider to write to your databases remotely if you host is not local.

Using Google, search “What is my IP address?” and it will typically return with your IP address assigned by your internet provider. Note this number which should be 4 groups of numbers separated by decimal points. EG: XXX.XXX.XXX.XXX .
From your server’s control panel, navigate to “Remote MySQL®”.
Enter your IP address into the “Add Access Host” and save it to the list.

Step 3: Setting up the database structure / creating a new table
Now a table to store all the data in needs to be created within the newly created database.

Open up the database admin. This may be called something similar to “phpMyAdmin”.
Click on the database you would like to add the table to.
Find “Create Table” and give the table a meaningful name. For this example, we are going to be saving the air quality data, so naming it “AirQuality” would probably be best.
Count out the number of columns you will need for the data you will be saving – do not forget one for the date/time either.
Once the table is named and created, the columns will next need to be named and parameters set. This is where things get a little more difficult.
Save the results. Now a empty table within your database is ready to accept data.
Here is an example of the Air Quality table with the columns named and parameters set.

Additional columns can be created later on and parameters changed if the settings are not right first time around.

Step 4: Configuring the PHP Scripts
Provided in the “Receiver Software Release v6.x” package are two files titled “AirQuality_LogToSQL.php” and “db_rw_details.php”. These need to be configured to match what has just been created on the server.

Open “db_rw_details.php” and set the credentials. Remove the X’s and replace with your personal details between the quote marks.
- $key ="xxxxxxxxxxx"; - This is a “handshaking” code which will be checked when data is passed from the outside source to ensure it is legitimate.
- $dbhost = "127.0.0.1"; - Usually does not need to be changed. The IP address could be replaced with “localhost”.
- $dbuser ="xxxxxxxxxxxx"; - This is the username which was setup in Step 1 of this guide.
- $dbpassword="xxxxxxxxxxxx"; - This is the password which was setup in Step 1 of this guide.
- $database ="xxxxxxxxxxxx"; - This is the name of the database which was setup in Step 1 of this guide.

Open “AirQuality_LogToSQL.php” for configuring this file.
Locate and update the “include” line in this file. This is used to point the path to read the credentials set in the “db_rw_details.php”. It is best if these two file are not located in the same folder for security reasons. An example of this is:
include ('/home/weather/data/scripts/db_rw_details.php');
- Locate the timezone setting and update this to your location. The following website can help choose the best timezone name to use for your area: http://php.net/manual/en/timezones.php . Example of this is:date_default_timezone_set('Europe/Lisbon');
- Choose the path of where the text log should be stored. This is a one line text file which get updated each time the data is uploaded to the website. For example:$logfile = './logs/AirQuality_Log.txt';

Save and upload these two files to your chosen directories on your website.

Step 5: Configuring the Software of RX Unit
The final step is to change the settings on the RX software so it knows where to access the files that have been uploaded to our website.

Navigate to the “Credentials.h” file.
Update the “My Server Credentials”.
- Under “My_Server”, enter your website address. NOTE: Do not use a leading http:// as this will not work.
- Under “Path_To_LogToSQL_PHPfile”, enter the path to the “AirQuality_LogToSQL.php” file on your website.
- The “MYSERVER_KEY” is where your “key” set under Step 4 is entered. This is the “handshaking” code which will be checked when data is passed from the outside source to ensure it is legitimate.

Within the “Config_Options.h” file, the “ENABLE_AQM_TO_MYSERVER” will need to be enabled by changing the “0” to a “1”.
Assumptions have been made that WiFi has been enabled and configured already within the RX Software settings. This is also a requirement if it has not been enabled.

Once the RX software is compiled and uploaded, it should now start to upload data to the database. This can be checked by logging into the database admin where the data can be viewed.

The data can now be pulled from this database for such things like producing graphs on the website and for many other purposes.

There is a lot of potential going forward for this to not only upload data for the Air Quality monitor (which at time of writing is the only publicly supported option). In the future, this concept could be used to upload all the data gathered by the weather station and have the weather station save the data directly into the database making it a free standing product.

Using SQL Language
Step 3 in this guide could be done by using SQL code if that is of personal preference. “Uncle_Bob” has done some work in this area. This is an example of the SQL code used to create a table within a database, once again using the Air Quality parameters.

Code:
DROP SCHEMA IF EXISTS `AQM`;

CREATE SCHEMA AQM;

USE AQM ;

DROP TABLE IF EXISTS `AirQuality`;

CREATE TABLE `AirQuality` ( `LogDateTime` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, `PM25` decimal(4,1) NOT NULL, `PM100` decimal(4,1) NOT NULL, `AQI` decimal(3,0) NOT NULL, `CO2` decimal(5,0) NOT NULL, PRIMARY KEY (LogDateTime) ) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Testing PHP scripts to ensure it writes
A web browser can be used to test the PHP scripts to ensure they write. As an example, this URL if entered into the web browser, should write data into the Air Quality database if it has been set up correctly (change the URL to find the "AirQuality_LogToSQL.php" file):
www.YOURSERVER.XXX/AirQuality_LogToSQL.php?privatekey=YOURKEY&PM25=99&PM100=98.7&AQI=97&CO2=96
Once the web browser loads the page, nothing will be displayed. But if the database is viewed, the data listed in the URL should have been entered.

Good job, Palmyweather!

Wish this thread existed a month or so ago Wink

Like Palmy mentioned, to automagically create the DB just copy and paste the above code into the SQL tab in phpMyAdmin and then hit go. Like the below image:

Great article Palmyweather!

This article is making me think in an "How To" section in the WeatherDuino Wiki

I couldn't resist!
It's already in the WeatherDuino Wiki

That is why it wrote it the way I did, hopefully in a general "long life" approach which could be used on the Wiki and the forum.

It has taken me a few attempts at writing it that way, but I think/hope the results are okay.

The format is excellent, it took me less than 30 minutes to put it on the Wiki, keeping the original look . Smile

A new door is open in the Wiki

Once again thank you for your work.
