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 ...

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 ...

This project is a simple soil moisture monitoring system using an Arduino, a soil moisture sensor, and an LCD display with I2C communication. The system reads the soil moisture level and displays the ...

Soil Moisture Monitoring with Arduino – Circuit Diagram Fig. 3 shows the physical connection of the system, while Fig. 4 provides the schematic. In both diagrams, the sensor’s output signal pin is ...

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.
