DIY Arduino water meter with iPad display

TEAGUE Give Water from TEAGUE on Vimeo.

It’s another arduino stuff to be working on here. All related references are included:

Some of the folks over at Teague Labs have been noodling around with measuring water consumption. They’ve built a graphing water meter using a YellowJacket Arduino board with built-in WiFi and coolant flow meter from a PC cooling system to see how they used water around the office. Water conservation is major concern in many areas around the world. Tools that allow us to observe and correct our behaviors help us towards a path to sustainability. Schematics and source code are available if you want to try it out for yourself.

Brilliant SCADA System that failed

Sunday, September 19th, 2010

A friend of mine shared an article about software failures. it’s a good stuff to read, where we can avoid some mistakes that previously been made by software developers. there is a SCADA software there – some of the problems that I’ve been encountered too in my life. check this out:

http://images.nakedmaya.com/Troll-Link1-sm.jpgNet-Herald – a monitoring application for water supply companies. It was a complex client server application that would receive monitoring data from specialized hardware and store that data inside a SQL database. The client displays that data in different graphs, provides printable reports or sends alarm messages via SMS if a monitored value is not within its specified limits. I developed Net-Herald as a perfect fit for that specialized hardware that is provided by a local manufacturer. That way, so I hoped, I could profit from their sales leads and would find a smoother way into these water supply companies. The downside of course, was that my software would only work with their hardware. (more…)

Automated rain barrel watering system

To some crowds, irrigating a small garden is a relatively relaxing and sometimes therapeutic activity, well if you are a botany/biology nerd or desperately really need a hobby – but going away for any length of time can present a problem. The simple solution of course is to purchase a hose-bib/timer package from Home Depot for about $30 and set up a small drip system to efficiently water each plant or row of plants (rather than a wasteful sprinkler system). Going along with conserving water is using a rain barrel collection system to capture rain for later use thus eliminating or more likely reducing treated water consumption.

Adding a rain barrel complicates the system significantly as there isn’t much water pressure at its spigot compared to a standard city spigot which has somewhere around 40 psi. Also, if the barrel is empty, you don’t want your plants to die and thus you need to be able to detect that the barrel is empty and switch to city water.
