Thunderstorm Posted January 25, 2005 Report Share Posted January 25, 2005 Hiyas Someone might like these circuits. Ones a water level indicator, the other is a water sensor. The water level indicator circuit could be modified to include a solenoid that turns on when the last LED is lit and turns off when at the top mark again. anyway hope someone can find a use for them Water Sensor click here Water level indicator click here Thanx Peter Quote Link to comment Share on other sites More sharing options...
Wok Posted January 25, 2005 Report Share Posted January 25, 2005 This could work for people who wanted to set up an automatic water changer couldn't it? I mean it would be able to turn off the water supply if someone was doing a water change and had left the tap running. Quote Link to comment Share on other sites More sharing options...
Thunderstorm Posted January 26, 2005 Author Report Share Posted January 26, 2005 Hiya Yes the water level indicator could be changed to do that, instead of switching the buzzer, use it to switch a small relay which in turn can switch a solenoid that is connected to a hose. Thanx Peter Quote Link to comment Share on other sites More sharing options...
