If your Arduino soil moisture sensor isn't working, check these common issues: verify all wire connections are secure, ensure you're using the correct Arduino pins (A0 for analog, digital pin for ...

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 ...

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 Arduino UNO project details the creation of an Automatic Irrigation System using an Arduino Uno and a soil moisture sensor. The sensor measures soil moisture, triggering the water pump when ...

This Arduino Nano project uses a soil moisture sensor, two potentiometers and a relay to automatically control a device based on soil moisture levels. The relay is turned on below a minimum threshold ...

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 ...

Fig. 2: Circuit diagram of the digital soil moisture meter Front-end of the digital soil moisture meter is a simple soil moisture sensor head, built around a few easily-available parts. Working of the ...
