peteec Posted July 15, 2006 Report Share Posted July 15, 2006 hi,could use a ballcock with a microswitch on it,as something simple,depends if you need to know the l;evel or just a "low" level warning! Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted July 15, 2006 Report Share Posted July 15, 2006 Here are a couple. The second one with the relay can be hooked up to: a doorbell, chime or musical car horn etc. Quote Link to comment Share on other sites More sharing options...
Lakhan Posted July 20, 2006 Author Report Share Posted July 20, 2006 Hello Hotwaterwizard!Thanks for responding.The first simple circuit appeals to me as a newbie.Would you please clarify the foll:1) What is the wattage of R2, 2.2 meg?2) Is sonalert buzzer same as a piezo buzzer. Can we use the latter? 3) Can we use a 9v, 500 ma DC power supply instead of a battery?4) Will there be any unsafe leakage current into the water?5) What kind of probes would you suggest for the high level water tank ....and what kind of cables to connect to the circuit?Thanks in advance!

Lakhan Posted July 20, 2006 Author Report Share Posted July 20, 2006 Hi Everybody!Carrying the idea of a musical water level indicator a bit further,would'nt it would be great if the geeks out there could rack up their brains to incorporate the 16 pin, 12 tune Quote Link to comment Share on other sites More sharing options...
