This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

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 ...

Measuring soil moisture with time-domain reflectometry (TDR) sensors can aid in turfgrass water conservation efforts and help improve playing conditions. However, information is lacking on the ...

In an afternoon I built a smart sensor that reads and displays soil-moisture levels, light intensity, and temperature. Arduino uses open-source hardware and software, so I was able to borrow ideas ...

So, Instructables user dr.mcc built a moisture sensor that alerts you when you need to water a plant by using an emoticon. Using an Arduino, a moisture sensor, an LED matrix, and a few other parts ...

Time Domain Reflectometry (TDR) has emerged as an invaluable tool in soil science, offering precise quantification of moisture content ... efforts to streamline sensor deployment protocols and ...
