0phoi5 Posted July 25, 2018 Share Posted July 25, 2018 Hi all, I'm working on a project to track the water levels in a water butt in my garden. I plan on installing a DIY irrigation system, which will consist of a pump sitting in the water butt. As I don't want the pump to switch on when the water level is too low, to save it running dry, I wish to monitor the level of the water inside the water butt. I've researched around for the best method, but it's very difficult to judge which will work best and is most cost effective! So far, I've considered doing one of the following with a Raspberry Pi; A reed switch/sensor, with a magnet floating on the top of the water, inside a tube, in the water butt. When the magnet reaches a low point within the tube, the reed switch picks it up and trips. An ultrasonic sensor on the underside of the lid on the water butt 2 long metal rods, with current, sitting down to near the bottom of the water butt. When the current running between the rods drops, when the water goes lower than the tips of them, then a script will kick in. Any thoughts on these? Has anyone done anything similar or have any ideas? Thank you Quote Link to comment Share on other sites More sharing options...
