Smart Water Sensors to monitor water quality in rivers, lakes and the sea | Libelium

Libelium launched a Smart Water wireless sensor platform to simplify remote water quality monitoring. Equipped with multiple sensors that measure a dozen of the most relevant water quality parameters, Waspmote Smart Water is the first water quality-sensing platform to feature autonomous nodes that connect to the Cloud for real-time water control. Waspmote Smart Water is suitable for potable water monitoring, chemical leakage detection in rivers, remote measurement of swimming pools and spas, and levels of seawater pollution. The water quality parameters measured include pH, dissolved oxygen (DO), oxidation-reduction potential (ORP), conductivity (salinity), temperature and dissolved ions (Na+, Ca+, F-, Cl, Br-, I-, Cu2+, K+, Mg2+, NO3-).

The Waspmote Smart Water platform is an ultra low-power sensor node designed for use in rugged environments and deployment in Smart Cities in hard-to-access locations to detect changes and potential risk to public health in real time.

U researchers implement wireless water sensors

At Pamela Park in Edina, Chris Wennen , a graduate student in water resources science at the University of Minnesota, stands knee-deep in a pond, examining what resembles an enormous film canister.

The device is a wireless sensor that monitors water quality. It is one of five implemented in the Minnehaha Creek area.

Wennen said the sensors measure the levels of pollutants such as nitrate and chloride, as well as the amount of oxygen, pH, temperature, turbidity and depth of the water.

CSIRO deploys wireless FLECK sensor nodes to monitor water catchment

CSIRO has partnered with SEQWater to monitor the Lake Wivenhoe catchment in Queensland using 120 nodes powered by CSIRO’s FLECK smart wireless sensor network technology.

According to CSIRO, the FLECK sensors could be the platform for the next generation of water quality monitoring systems, providing real-time data collection with unprecedented detail and speed. The FLECK sensor nodes operate in a meshed network, setting up ad hoc networks to wireless transfer environmental data they have collected.

Using the technology, SEQWater and CSIRO will be able to monitor high rainfall, droughts and contaminants in real-time.  An autonomous solar-powered catamaran is also part of the solution, and it can be instructed by the network to carry out more detailed sampling as needed.

Seventy of the 120 nodes are land-based and spread across the catchment area, while 45 are floating and measure water temperature. The sensor system is manually controlled through a PDA, web interface, or web-enabled mobile phones.
