Smart Water

Water Management affects multiple sectors: agriculture, farming, industry, services, cities… We can monitor drinking water, detect and control realtime leakages in rivers and seas, track pressure variations along pipes and check water quality in fishfarms, swimming pools or aquariums.

Smart Water

The challenge

Population growth and climate change are the main challenges for water management.

Water demand is expected to increase up to 30% by 2050, increasing 1% per year.


Benefits of Water Management solutions

What water quality projects look for…


  • Recaptured revenue
  • Coordination and synergies between stakeholders
  • Predict potential failures
  • Manage pressure and consumption


  • Up to -10% reduction in water consumption per capita
  • Reduced leakage: -20% wastage reduction
  • Reduced billing
  • Cut down costs: maintenance, repairs and energy

Sound interesting… And which are the main applications of this technology?

Applications of IoT for Water Quality

Fish farming

Monitoring dissolved oxygen, pH levels or salinity is essential to achieve optimal health and growth.


Controlling water consumption/metering, distribution, irrigation, leak detection, storage (tanks, reservoirs, etc.) bathing water quality and detecting bacterial presence.


Prevention of chemical wastewater pollution, monitoring seawater desalination, hydroponics and water quality in ports.


Flood prevention, chemical leakage monitoring and water quality control after natural disasters.

Aquarium Management

Ensure animal welfare by monitoring parameters such as temperature, pH, Electroconductivity or Dissolved Oxygen
in real time.

Smart Water Products

Smart Water is designed to detect the most relevant water quality parameters such as dissolved oxygen, oxidation-reduction potential, pH, conductivity and temperature.

Smart Water Xtreme

Smart Water Xtreme | Plug&Sense! is an improvement of our Water line with a new selection of high-end professional sensors.

All sensor probes incorporate an integrated temperature sensor to compensate measurements. This process is called “integrated temperature compensation”.

Robust sensor probes: PVC and stainless steel. 5-6 bar pressure resistance.

A variety of mounting accessories for each sensor are available to be placed in pipes or tanks. Protective wildlife accessories are also available.

Available Sensors:

• Optical dissolved oxygen and temperature (OPTOD)
• Titanium optical dissolved oxygen and temperature(OPTOD)
• pH, ORP and temperature (PHEHT)
• Conductivity, salinity and temperature (C4E)
• Inductive conductivity, salinity and temperature (CTZN)
• Turbidity and temperature (NTU)
• Suspended solids, turbidity, sludge blanket and temperature (MES5)
• COD, BOD, TOC, SAC254 and temperature StacSense, 2 mm path
• COD, BOD, TOC, SAC254 and temperature StacSense, 50 mm pathRadar level
• Temperature, Humidity and Pressure
• Luminosity (Luxes accuracy)
• Ultrasound (outdoor IP67)

Sensors maintenance

    It is highly recommended to clean sensors every 2 weeks. Sea installations require more frequent maintenance.


Optical and anti-fouling systems require less maintenance.


Fouling effect occurs when there is organic materials in the water. It creates a “bio-film” which adheres to the probes and provokes wrong measurements → quality decreases.

    There are some anti-fouling methods:

    • Optical technology
    • Inductive technology
    • Brushes
    • Copper coverage
    • Led UV system

Wireless communication protocols available to connect devices

  • 802.15.4
  • ZigBee
  • WiFi
  • 4G
  • 868
  • 900
  • LoRaWAN
  • Sigfox
