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

NextPCB offers first 2-layer 100 X 100 mm PCB with 0$ : 4-layer PCB - 12$ : .................................................................................................................................................................................................................................... About the Project: 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 deficienc
