Remotely monitoring tank levels with Arduino and Xively

Monitoring tank levels of vital fluids for the home or business can be a difficult task, in some installations the level gauges can be older and inaccurate, or just not work that well. Which oftens leaves the user with filling up smaller amounts on a frequent basis to avoid runnning out, or using haphazard guesswork to determine the levels.

However with an Ethernet-enabled Arduino or compatible and some inexpensive sensors you can remotely monitor tank levels over the Internet, and at a much higher accuracy. This has been demonstrated by Arduino forum member dpslusser who uses an ultrasonic didtance sensor placed over the top of a tank to accurately determine the level of the contents.

With a prior understanding of physical tank levels and volume, an Arduino sketch can calculate the volume and report the level to the online service Xively - which can then convert the data into web-enabled dashboards for remote monitoring.

This project has many applications, from water to waste tanks, fuel and more - so login to the Arduino forum for more information and discussion. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

When putting together your next Internet-enabled Arduino or AVR project - save time, space and money with the  Freetronics EtherTen . Apart from being fully  Arduino Uno-compatible , it has onboard Ethernet, microSD socket, full USB interface (so you don't need a costly FTDI cable just to upload a sketch!) and supports optional  Power-over-Ethernet .
