Itron Aquadis+ watermeter sensor V1.0

mySensors Watermeter

Adapted mySensors Arduino sketch for measuring pulses on a (standard) household watermeter.

The development was initially done for a Itron Aquadis+ watermeter, but can be adapted for any other watermeter that has the ability to read one of the rotating counters externally.

For more info and dicussion on this project, visit the mySensors forum thread.

[edit 2017-02-19] Finalised the design files as this project is finised. Will start working on a version 2.0 (separate project) with embedded Atmel processor and potentially RFM radio.
