Insert the 2 probes (wires, pcb) in the dry soil and measure the resistance value and then pour water and measure it again. Use a mid value for the resistor (eg: 50kΩ for 100kΩ in dry soil and 10kΩ in ...

Adding sensors to your Arduino opens up a whole new world of exciting projects. ... Measuring the pH level of a water source can give you a range of information about the liquid.

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 ...

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.
