Irrigation Embedded Control System

Description

This project is an embedded control system designed for managing irrigation effectively. Utilizing a Nucleo F401RE board, this system integrates various sensors and actuators through a custom-designed PCB, enabling automated water distribution based on real-time environmental data.

System Overview

• MCU Controller: Nucleo F401RE Development Board
• Sensors: Interfaces for US100 water depth sensor and other environmental parameters
• PMW Motor Control: Includes L9110 motor speed control for pumps and MG90S servo motor control for valves
• Buffers: Includes CD74HCT541 and CD74HC4050 for logic level translation
• User Interface: Input and indicator interfaces for real-time control and monitoring through UART protocol
