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 ...

We learned about RS485 Serial Communication between Arduino Uno and Arduino Nano in the previous tutorial. This tutorial is about using a RS-485 Serial communication in STM32F103C8 Microcontroller. If ...

Industrial-Grade Soil Sensor: Measure multi-parameters of soil including Temperature, Moisture, pH, EC and Nitrogen, Phosphorus and Potassium (NPK). The output signal is RS485 and can be operated ...

In RS-485 Modbus network there is one Master and 127 Slaves each with unique address from 1 to 127. In this MAX485 Arduino project, we will use Arduino Uno as Slave for serial communication. Modbus ...

Phosphorus and Potassium (NPK) which consists of an optical sensor. The optical sensor is developed with two systems which are transmission system and detection system. The transmission system uses ...
