NPK Sensor
Overview-
The soil nitrogen, phosphorus, and potassium (NPK) three-in-one fertility sensor is suitable for detecting the nitrogen, phosphorus, and potassium content in the soil.
It is ideal for various agricultural experiments, especially concerning food production.
How it works-
The NPK sensor monitors the dielectric constant of the soil.
It can directly and stably reflect the true moisture content of various soils. It can measure the volume percentage of soil moisture and calculate the NPK concentrations.
