This project involves interfacing an Arduino Uno with the NPK 7-in-1 Soil Sensor to measure various soil parameters including moisture content, temperature, electrical conductivity, pH level, nitrogen ...

The NPK Sensor System reads soil nutrient levels (Nitrogen, Phosphorous, and Potassium) using a sensor module and displays the values on an OLED screen. It communicates with the sensor over Modbus ...

Soil is the most important medium for plant growth. The aim of this project is to develop a detection system for major nutrients of soil; Nitrogen, Phosphorus and Potassium (NPK) which consists of an ...

In this review, we have evaluated several methods and recent technologies to determine the soil nitrogen, phosphorus, and potassium (NPK) content to increase yield production. Sensing technology has ...
