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 :
  1. flow - _liters per minute _
  2. volume - _liters per day _
  3. pulse - _counter pulses _
  4. leak - _leak (0 : no leak, 1 : continuous consumption during 24h, 2 : consumption in excess of 24h threshold ) _
  5. pulse factor - _pulses per m3 - by default 100 _
  6. leak threshold - liters per day - by default 800 l/day
