Innovative water quality monitoring using IoT sensors

Water quality is crucial for effective water management. Whether it's for supplying drinking water, treating wastewater or monitoring water quality, continuous measurement is an indispensable tool for protecting people and the environment, and ensuring the sustainable use of water.

Table of Contents

Water quality measurements are used to monitor various water parameters that provide information about its chemical, physical and biological properties. The most important of these include pH value, oxygen content, temperature, conductivity, and the concentration of pollutants such as nitrates, phosphates, and heavy metals. Regular monitoring of these parameters enables pollution or changes to be recognised at an early stage, allowing appropriate measures to be taken.

Areas of application

  • Drinking water supply:
    Measurement and monitoring of water quality parameters at various
  • Wastewater treatment and disposal:
    Monitoring of purification processes in wastewater treatment plants
  • Water monitoring:
    Monitoring of surface waters, such as rivers, lakes, and coastal waters

Digital multiparameter sensors

The following sensors are suitable for both stationary operation with a fixed voltage supply and energy-self sufficient operation with a battery, rechargeable battery or PV combination. They are connected via an RS485/Modbus interface and can be powered by the data logger.

Analogue sensors for use in ATEX areas

These sensors are designed using 2-wire technology and output the measured variable as a 4–20 mA signal. The sensors are supplied via the data logger. The listed sensors are available from their respective manufacturers as ATEX variants and can be used with our data loggers in ATEX areas.

Everything at a glance – local display applications for data loggers

Microtronics data loggers are easy to commission and configure via the web interface of the myDatanet portal. As soon as the device is in operation, the collected data is transferred to the platform where it can be visualised, evaluated and , if necessary, further processed.

For some applications, however, there is also a need to display information and measurement data directly on the device. In the following article , we present two solutions for local display and operation.

Securing water for future generations: implementing Water Vision 2100

Water is one of our most precious resources, but its sustainable use is becoming increasingly challenging. Climate change, increasing consumption and environmental pollution require innovative approaches to secure water supplies in the long term. The Water Vision 2100 of the Austrian Water and Waste Management Association (ÖWAV) and the Austrian Gas and Water Association (ÖVGW) shows what measures are necessary to protect water for future generations.
