It was around 9 bars! Ever since I was looking for a way to monitor the water pressure and also had my eyes on monitoring flow and some water quality parameters.<\/p>\n<p style=\"text-align: left;\">A few weeks ago I took the first step and got an <a title=\"IO-204 Monitor and Control Module\" href=\"http:\/\/products.iobridge.com\/io-204-monitor-and-control-module\/\">IO-204 Monitor and Control Module<\/a> from <a title=\"ioBridge\" href=\"http:\/\/www.iobridge.com\"><span><span>ioBridge<\/span><\/span><\/a>. The IO-204 module is a gateway to the World Wide Web\u00a0connecting devices to the Internet. The module has four channels each with an\u00a0analog input, digital I\/O, pulse count, +5v DC Power and ground. This operation, of connection stuff to the web is called <a title=\"Internet Of Things\" href=\"http:\/\/en.wikipedia.org\/wiki\/Internet_of_Things\">Internet Of Things<\/a> (IOT). The <em>thing<\/em> can be any device, even\u00a0a <a title=\"Social Networking for My Toaster\" href=\"http:\/\/iamshadowlord.com\/2008\/12\/social-networking-for-my-toaster.html\">toaster<\/a> like this guy did connecting his toaster to <a href=\"http:\/\/twitter.com\/mytoaster\">Twitter<\/a> (also done with an IO-204 module).<\/p>\n<p style=\"text-align: left;\">Before I can connect the <em>things<\/em><span>that interest me to the web I had to do some learning and my first testing &#8220;project&#8221; is ready. Its somewhat ridiculous and simple but I did learn a lot from it. This small project has two sensors: one is an analog input (AI)\u00a0and the other is digital (DI). The two inputs are shown, over time, in the two next on-line charts (I have made them load with a short delay to allow the full page to load first). The\u00a0first is the AI showing three days of data in 12 minutes intervals. For some reason, which I could not fix, the time is shifted by two hours back (12am is actually 2am). The data logging and chart is one of the services you get from <span>ioBridge<\/span> with the IO-204 module.<\/span><\/p>\n<p style=\"text-align: left;\"><a href=\"http:\/\/www.water-simulation.com\/wsp\/wp-content\/uploads\/2011\/05\/ai-graph.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-873\" title=\"Analog input\" src=\"http:\/\/www.water-simulation.com\/wsp\/wp-content\/uploads\/2011\/05\/ai-graph.jpg\" alt=\"Analog input\" width=\"369\" height=\"151\" \/><\/a><\/p>\n<p style=\"text-align: left;\">The second chart is the DI also showing three days of data but data is logged only when there is a change in the sensor&#8217;s state.
