Our kitchen hot water tap is always getting left on because it is low flow and you cannot hear it running - and there is no point in shouting at the f amily because there is only two of us here and we are both guilty. And, ye s - I've shouted at her and I've shouted at myself- all to no avail.
So, I can do electronics and micro-processors and I thought there is a solu tion there, but putting a timer, a sensor on the hot water pipe and a bleep er is not going to work as the pipe will remain hot long after the tap has been put off - ditto doing that on the waste pipe. So I need a flow sensor to detect the tap has been shut off so that the bleeper doesn't start fals ely and to stop it immediately when it does do its duty. But is there some thing inexpensive that will do that ?
Thanks for any ideas. Rob
