About this product
A soil moisture sensor with two probes that passes current through the soil and reads its resistance to estimate moisture. Wetter soil conducts better and gives lower resistance, while dry soil gives higher resistance. It suits plant watering reminders and garden monitoring, and works with Arduino through the IO Expansion Shield.

Where can I buy Soil Moisture Sensor (Two-Probe Resistive) in Egypt?
Soil Moisture Sensor (Two-Probe Resistive) is available from RAM Electronics and Future Electronics. Compare the offers above to find the best price.
How does the reading relate to soil moisture?
Water helps soil conduct electricity, so wetter soil gives lower resistance between the probes and drier soil gives a higher one. Compare readings in your own soil to choose a watering threshold.
How do I connect it to an Arduino?
Use the IO Expansion Shield. Plug the sensor into the matching port on the shield, check the labelled pins, then read the sensor value in your Arduino sketch.
