DIY Soil NPK Meter || Measure Soil Nutrient Content using Soil NPK Sensor & Arduino

In this video, we will learn about the interfacing of Soil NPK Sensor with Arduino. The soil nutrient content can be easily measured using NPK Soil Sensor & Arduino. Measurement of soil content N (nitrogen), P (phosphorus), and K (potassium) is necessary to determine how much additional nutrient content is to be added to soil to increase crop fertility.

The soil fertility is detected using NPK sensors. A major component of soil fertilizer is nitrogen, phosphorus, and potassium. The knowledge of the soil nutrient concentration can help us to learn about nutritional deficiency or abundance in soils used to endorse plant production. Apart from measuring Soil NPK, you can also measure Soil Moisture Content using Soil Moisture Sensor, which is explained in my one the previous video.
