This repository contains the code for a Nitrogen, Phosphorous, and Potassium (NPK) Sensor System using an Arduino. The system reads the NPK values from a sensor and displays them on an OLED screen.

Sensor NPK adalah sebuah sensor yang digunakan untuk mengukur zat hara pada tanah yang mana nilai yang diukur adalah Fosfor, Potasium, dan nitrogen dengan satuan mm/kg untuk membaca nilai yang dibaca ...

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 ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...
