The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

In a way, the magic of a soil moisture sensor’s functionality boils down to a simple RC circuit. But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how ...

Like this low-power soil sensor project and the custom controller for six soil sensors, [rbaron’s] w-parasite uses a “parasitic capacitive” moisture sensor to determine if it’s time to ...

This humidity sensor consists of 2 copper conductors that are located at small distance from each other. The relay switches as soon as the moisture makes a connection that is more or less electrically ...

My soil-moisture reading was in the low 700s in soil that had around 30 percent moisture (according to a comparison with a commercial soil-moisture sensor), and 661 in a drier pot.

BEAVERTON, Oregon — Vernier Science Education recently launched the Go Direct ® Soil Moisture Sensor to help high school and college-level students easily and accurately collect data during soil ...

Smartrac has released a moisture-sensing passive ultrahigh-frequency (UHF) RFID tag known as the Sensor DogBone that is intended to launch innovation in moisture sensing. The company began shipping ...

Oso Technologies' PlantLink is hoping to usher your garden into the Internet of things. The $79 package consists of a "Basestation" that you can attach to your Wi-Fi router, and a moisture sensor ...

We report the design and installation of a distributed soil moisture sensor network in a riparian zone within the Whitewater Basin in Central Kansas. The soil-moisture monitoring network used in this ...
