    Haha same!

  • High Precision Scale with Arduino about 3 years ago

    Interesting project. How much did the materials cost, and how long did it take to complete? As well, if the precision of the weight sensor could be increased, then this can become a viable alternative to a commercial analytical balance (+/- 0.0001 g or better).

    Glad that you enjoyed reading about this project!

    The water comes from a garden hose, which is fed from the utility tap water supply. Then, the water is released using an oscillating lawn sprinkler (for the lawn) and a watering shower attachment for the flowerbed.

    Regarding the valve, another option I have considered is a servo connected to a hand turn valve. This would definitely save power, but I have yet to come up with a good design for such a setup. As for the flow meters, I will look into it. In the meantime, since tap water pressure is largely constant and the flow rate through the sprinklers is constant at a given pressure, the time which the valves are on provides a useful proxy for the amount of water delivered and can be used for water usage analytics.
