I scavenged the net but wasn't able to find a more or less ready made optical sensor for getting a pulse from my gas meter. The gas meter has a small mirror on the last digit 6.
Is there someone out there who has connected a similar gas meter to a Flukso?
What I'm after is a sensor which I can build myself as I'm fairly handy with a soldering iron.
An idea I came across: use a CNY70 (but how?) eg. http://www.jojos-homepage.de/ft/cny70/index.html
The jpg of the meter is attached.
Thanks, all ideas are welcome. - Jos
