SoilWatch 10

SoilWatch 10 is a soil moisture sensor which allows you to measure relative water content in the soil. It’s far more superior to cheap resistive soil moisture sensors which you can buy anywhere. In our sensor design, there are no exposed electrodes which corrode within few weeks. Whats more the reads will almost not drift over time or with temperature changes. Our sensor will give the same readings regardless of supply voltage. Sensor design makes it waterproof and weatherproof. It can be buried in soil for an extended period of time without adverse effects on accuracy.


  • Accurate
  • Easy to use
  • 75Mhz capacitive sensor
  • Waterproof and weatherproof proof
  • Will last a lot longer than resistive soil moisture sensors


  • Irrigation management
  • Soil moisture monitoring

    This is my second order of these sensors because these are the only soil moisture sensors which are affordable and will work month after month. Highly recommended.
    By the way, I ordered them not because the first ones were broken, but because I am expanding my garden system.

    I love this product, it is usually difficult to find sensors of this type that operate uniformly on different types of soil. He fulfilled all my expectations.
