Lora Wan irrigation system controller
Budget: €1,500 – €3,000 EUR
Project Description: PLC and LoRa-Based Solar-Powered Irrigation Control System
Project Objective:
The goal is to develop a wireless, solar-powered irrigation control system for an agricultural area. The system should be able to remotely control solenoid valves located at multiple points in the field and start/stop a water pump at the pumping station. There is no fixed power supply at the site; all components must operate using solar energy. The central control will be handled via a PLC (Programmable Logic Controller).
⸻
Main Functions:
1. The central PLC will:
• Send commands to various LoRa nodes across the field
• Control the pump start/stop remotely
2. LoRa nodes will:
• Control solenoid valves based on commands from the PLC
• Be powered by solar panels and batteries
• Communicate using LoRa modules
⸻
Technical Requirements:
• Central PLC:
• Will be connected to a LoRa module (via UART, SPI, or RS485)
• Capable of sending commands to LoRa nodes (via Modbus RTU or a custom LoRa P2P protocol)
• LoRa Nodes:
• Equipped with a LoRa module (e.g., SX1276/SX1278, RFM95, or E22-900M30S)
• Use a microcontroller (e.g., Atmega328P, STM32, or similar)
• Include relay or MOSFET output for controlling solenoid valves
• Powered by a solar panel, Li-ion battery, and charging/power management modules
⸻
Expectations from Freelancer:
• Set up communication between PLC and LoRa module (or use an external LoRa gateway)
• For each LoRa node:
• Develop firmware to receive commands and control outputs
• Implement low-power modes (e.g., deep sleep) for energy efficiency
• Provide circuit schematic and component list
• Optional: Create a Modbus-compatible or custom communication protocol
⸻
Additional Information:
• In the next phase, the system may be expanded with sensor data collection and LoRaWAN integration.
• Preferred communication languages: Azerbaijani, Russian, or English
