The sensor's water circuit is designed to reach approved water flow rates with lower pressure requirements. The sensor also features an over-temperature sensor that triggers an LED indicator ...

The clever thing here isn’t so much that it’s based on the tiniest of Raspberry Pis, but how it keeps track of the somewhat obscured water flow information coming from the meter. Using a ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water.
