Frequently Asked Questions
How does a soil moisture sensor work?
Soil moisture sensor measures the amount of water present in the soil by using several properties, for instance, electrical conductivity/resistance, dielectric constant, or interaction with other materials to record the moisture level in the soil.
What is the purpose of a soil moisture sensor?
As the soil moisture sensor senses the amount of moisture in the soil, it can help in maintaining the optimum/ideally required amount of moisture in the soil to maintain healthy conditions for plants. It also enables us to inform the amount of water a plant should be given.
How do you test a soil moisture sensor?
Different soil moisture sensors are tested in different ways:
Firstly, dry soil is taken, and the soil moisture is calibrated according to its ideal moisture level then the device can be used on the soil. If it indicates below the calibrated value, that means moisture is less in the soil and vice versa.
