Specifics The weather-resistant sensor on the ECOWITT Soil Moisture Tester takes accurate moisture readings in about 72 seconds and displays them on a convenient LCD display. Soil moisture level ...

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 ...

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 ...

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 ...

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 ...
