Much like the low-fluid warning light in a car, a new wearable sensor linked to a smartphone app is set to alert people when their hydration levels are dangerously low. The device could be a big help ...

A new self-powered water sensor uses wave energy to monitor pollutants like heavy metals, microplastics, and pesticides - no battery needed. The innovation integrates two core components. First, a ...

Water Distribution Systems (WDS) are critical infrastructure assets that deliver water from source to consumers. The increasing scarcity of fresh water has heightened ...

Abstract: Emergence of Controlled Environment Agriculture (CEA) ranging from computer controlled water irrigation system to lightning and ventilation has changed the conventional scenario of farming.

We love Arduino here at Hackaday; they’ve probably done more to make embedded programming accessible to more people than anything else in the history of the field. One thing the Arduino ecosystem is ...

Abstract: We connected $\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The ...

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. Researchers have developed a new optical sensor ...

The U.S. has experienced a drop in water usage per capita over the last two decades. As an example, from 2005 to 2015, a significant decline in surface freshwater withdrawals was observed in 64% of ...
