Crop Tattoos: Wearable Sensors Measure Plant Water Use A promising peel-and-stick crop sensor may provide farmers with actionable information on the real-time drinking habits of their crops. From ...

CropX makes sensors and software designed to help farmers determine precisely how much water to use in different parts of their fields.

Born from the experience of the Kerala flood, TK explores how to make a simple water quality meter with a turbidity sensor. This simple project shows the theory and basic components to build a ...

This Snap-On Sensor Could Tell Farmers Exactly How Much To Water Their Crops A team at Penn State University is developing a clip-on leaf sensor that measures water stress on individual plants ...

In this article, we focus on the use of graphene in water sensors, exploring how these sensors detect common contaminants, including heavy metals, microbes and irregular pH.

Flood sensors come in all varieties, but they pretty much all work using the same mechanism: when water touches two exposed metal probes, the device senses increased conductivity between those ...

His revamped water level sensor relies on measuring capacitance changes in a copper strip board when under water rather than detecting a complete circuit like the previous model.
