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 ...

Taste The Code. Working with a Capacitive Soil Moisture Sensor. Posted: June 12, 2025 | Last updated: June 13, 2025. Hi, I'm Bill. I'm a software developer with a passion for making and electronics.

Posted in Arduino Hacks Tagged capacitive sensor, ESP32, Rain sensor, sensor. ... explains exactly how capacitive soil moisture sensors work simply, clearly, and concisely.

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.

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.

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 ...

We use the built in capacitive touch measurement system built into the ATSAMD10 chip, which will give you a reading ranging from about 200 (very dry) to 2000 (very wet).

In order to achieve this goal, a printed soil moisture sensor fabricated from biodegradable materials is demonstrated. These devices are intended to function during the growing season and then ...
