Access to physical sensors & appliances control in real time

Hi,
Just different post - not to solve some issues - but to show some opportunities
It's very easy with nuBuilder to analyse, present and process all data stored already on computer disc.
But access to physical sensors, equipment or even to control appliances in real time - it's not more difficult
Just recently I've bought Arduino with some sensors (in total 15USD) and was trying to connect it to nuBuilder - and it was very easy.
The big benefit is that Arduino can connect to web server therefore you can use php files to perform any tasks and communicate both ways.
It's a kind of fully mobile system - which can connect to the database from any part of the world - and the only condition is the access to the network.
If you are interested in such solution please find short movie how it works.

If anyone would be interested to get some more details - I can provide.

Hi Janusz!
What a neat example! If I ever get to buy Arduino too, I'll certainly ask you for details on the implementation.
BTW: I suppose you use apaxcharts (instead of google charts)

Janusz,
That is really interesting.
It opens up so many new worlds.

Hi,
I prepared a YouTube video for Polish Arduino users. It is not in English, but maybe some of you know Polish
So overall the video is not much different to the one I posted earlier - but with some improvements made to the app. and with more focus on the nuBuilder.
So if someone would be interesting to see - link is just belowe.

The only Polish I know is a bit of reverse Polish notation. Thanks for this post. I am automating our production line and just got an Arduino UNO working with sonar sensor to monitor the level in a sawdust hopper. I have made a Java HMI for Arduinos for previous projects. I'm looking forward to integrating nuBuilder into our production line. At least you code in English. Thanks!

Hi treed,
I'm glad that other people here are using Arduino. If you would need some more details - just let me know and I can share.
In the example here I use Arduino WeMos D1 as it has wifi module included so connection to local wifi network do not require any additional modules to install.
And if it's connected to the network then data exchange with mysql database is very easy. Just to call php procedures from Arduino code:
(some example)
Code: Select all
//GET method - read from MySql
http.begin(server_2arduino_url);
http.GET();
String data = http.getString();
http.end();
Code: Select all
//GET method - wtite to MySql
http.begin(arduino_2server_url+"?temp="+String(temperature)+"&hum="+String(humidity)+"&temp2="+String(temperatureC));
http.GET();
http.end();
the urls can be as following:
Code: Select all
const String arduino_2server_url = "http://192.168.6.105/ArduinoDB/arduino1.php";
const String server_2arduino_url = "http://192.168.6.105/ArduinoDB/arduino2.php";
const String arduino_sampling_url = "http://192.168.6.105/ArduinoDB/arduino3.php";
in the php you can place any code you want.
