Automation of Agriculture With IRIV IO Controller

Project description

This project uses an IRIV IO Controller to automate irrigation: it reads soil and ambient conditions from RS-485 (Modbus RTU) sensors and drives a 24 V DC relay (water pump) based on moisture thresholds. Data is visualized in a Blynk dashboard via Ethernet (WIZnet W5x00, CircuitPython). The tutorial lists the exact sensors, wiring, Modbus register map, and a working example. 🔧 Project Overview Project Name: Sample Application: Automation of Agriculture with IRIV IO Controller Author (Tutorial): Hussien Jawhar Sathik (Cytron) Platform: IRIV IO Controller (CircuitPython) Networking: WIZnet…
