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 soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

My shed is mostly done, which means I'm moving onto other projects that look a lot like landscaping. Lawns, gardens, etc. I want to be efficient in my watering, and potentially even lazy and have ...

Adding sensors to your Arduino opens up a whole new world of exciting projects. Here are some of the best sensors around. MUO. 8 Unique Sensors for Arduino Microcontroller Boards.

Capacitive soil moisture sensors don’t have the same problem. Resistive ones are the ones that have that electrochemical reaction and are why when I first got some I stayed clear of resistive ...

This LoRa node used off-the-shelf components consisting of an ATmega328P-based Arduino Pro Mini ... as part of a discussion around all of the problems associated with standard soil moisture sensors.

“Most low cost soil sensors are resistive style, where there’s two prongs and the sensor measures the conductivity between the two. These work OK at first, but eventually start to oxidize ...

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.

The sensor’s moisture element is unique because it works similar to a plant’s root by measuring water tension in its hydrophilic fabric-covered matrix material rather than the surrounding soil.
