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 ...

Arduino Board: The main microcontroller used to interface with the sensor and the LCD. Soil Moisture Sensor: A sensor used to measure the moisture level in the soil. LCD Display: A 16x2 character LCD ...

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 ...

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 ...

To build this soil indicator system, we have used LCD I2C along with electronic components Arduino Nano, Soil Moisture Sensor, Bread Board, Arduino Nano Cable, Jar filled with soil. The Soil Moisture ...

Calibrate the sensors to ensure accurate readings. This involves setting baseline values for both the accelerometer (zero-point calibration) and soil moisture sensor (dry and wet calibration).

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.
