Mysensors Watermeter
Technical Specification
Designed to fit in a 3D enclosure available on Thingiverse
https://www.thingiverse.com/thing:3812171
Small footprint, 61 mm x 52 mm
Arduino nano and nRF24L01 boards
Onboard LED for ERROR and leak detection
Powered and programmed over USB.
Functional Specification
Measure volume and flow of your house water meter.
You need to set the correct pulsefactor of your meter (pulses per m3).
The sensor starts by fetching current volume reading from gateway (VAR 1).
Reports to gateway :
flow - _liters per minute _
volume - _liters per day _
pulse - _counter pulses _
leak - _leak (0 : no leak, 1 : continuous consumption during 24h, 2 : consumption in excess of 24h threshold ) _
pulse factor - _pulses per m3 - by default 100 _
leak threshold -
liters per day - by default 800 l/day
