Capacitive Soil Moisture Sensor Arduino – In this tutorial, you will learn how to use the Capacitive Soil Moisture Sensor v1.2 with Arduino and display the Soil Moisture value on a 16×2 i2c LCD module. The soil moisture is monitored in real-time.

With the SparkFun Soil Moisture Sensor, you can do just that! This tutorial will show you how to get started using the Soil Moisture Sensor as well as how to build your own soil moisture sensing project. If you prefer not to solder, you can purchase the sensor with a 3-pin screw terminal pre-soldered onto the board.

Jan 4, 2024 · Let's see how the circuit is designed to function: Referring to the circuit above, the design makes use of a single IC 741 opamp comparator for the required testing function. The pin3 which is the non-inverting input of the opamp is used as the main sensor probe with respect to the other probe connected with the ground.

May 1, 2025 · 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 connected to A0 pin of the Arduino board. VCC and GND pins of the sensor are connected to the Arduino’s 5V and GND pins, respectively.
