The concept of the internet of things, known as IoT or connected networks is that any device should be able to connect to another device as well as to the internet. This connected network is possible due to the advancement in communications networks and device technologies.
Whilst the number of devices currently in use is hard to estimate, Gartner and other sources talk in the order of 30 billion devices in 2020.
Internet of Things for Water Utilities
IoT sensors can provide immediate benefit to water utilities that includes;
- monitor water quality at various consumer endpoints in the network,
- real-time IoT platforms with predictive analytics,
- reducing electricity consumption in water and wastewater treatment,
- tracking the performance of pumps and their operational characteristics more efficiently.
Currently the number of sensors available is extensive and some of the categories include;
- Force / Load / Torque / Strain / Pressure
- Leaks / Levels
- Electrical / Magnetic
- Acceleration / Tilt
- Machine Visions / Optical / Ambient Light
- Position /Presence / Proximity
- Motion / Velocity / Displacement
- Humidity / Moisture
- Acoustic / Sound / Vibration
- Chemical / Gas
The introduction of LPWAN has enabled IoT devices to be vendor lock-free, removing one of the major hurdles that have existed. LPWAN is also allowing devices to be installed at the site without electricity and or traditional mobile coverage.
The installation of sensors through sewerage networks can ensure prior knowledge of surcharges and spills. There will be a strong environmental protection driver to engage in this technology immediately.
