This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain ... I love all about electronics, circuit diagrams and crazy projects that can help us achieve almost ...

If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

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 ...

Why not use it to save my ailing amaryllis? In an afternoon I built a smart sensor that reads and displays soil-moisture levels, light intensity, and temperature. Arduino uses open-source hardware ...

Soil moisture sensors can help farmers save water, by letting them know when their crops actually need to be watered. An experimental new sensor could be particularly helpful, as it incorporates a ...

a 2022 paper by Maja Škiljo and colleagues in Sensors covers an interesting way to make use of this signal attenuation property of changing moisture levels in soil. By quantifying the exact ...

For example, at optimized sensor positions and angles on smooth soil, increasing the soil moisture content from 5% to 30% decreases the transmission efficiency from ~46% to ~3%. A thermal camera ...
