The sensors for monitoring different parameters in smart cities are becoming a hot topic for researchers all around the world. The smart grids are one of the main objectives of the smart city concept.

Dissolved oxygen (DO) is the measure of oxygen gas that is physically dissolved in water. It is a critical parameter for ...

The sensors automatically detect rising water levels and provide early warnings about high water levels or flooding, and ...

Detecting the presence of lead in potable water due to insufficient water treatment or transport through lead pipes is ...

Scientists have pioneered a new way to monitor sodium levels in the blood—without drawing a single drop. By combining terahertz radiation and optoacoustic detection, they created a non-invasive system ...

When using non-contacting radar technology to measure level in tanks, internal obstructions can interfere with signals and ...
