water meter and ds2423 problem
Posted: Thu Aug 18, 2011 9:41 pm
in my new house i installed 3 watermeters from aquatel, wich have a pulse connector.
Normally the reed contact is open (no connection), but when the magnet passes the reedcontact closes.(connection) (and could stay closed when the meter stops on the magnet).
I tried connecting this sensor between the ds2423 A connector and the +5V. But i get strange readouts...
So i went looking, and it seems when I connect the A connector with 5V i get an incement of the counter(so thats ok), but more than one (seems to be related to the time it's connected.)
Does anyone have a solution for this problem ( or a working schema?)
Thanks!
