FPGA-based climate for a greenhouse

Abstract

This report describes the design and implementation of a climate controller for a greenhouse automation system. It deals with controlling different environmental parameters inside a greenhouse that ensure the growth requirements of plants. The approach to design this digital controller is the SoPC technique and it is implemented using both hardware and software components. The prototype for this project consists of four parts, the On-chip system integrating the Nios II soft core processor along with an on-chip memory, I/O peripherals, UART port and custom VHDL blocks. The off-chip system that includes different motor driving units, actuators and data acquisition unit. The smartphone that runs an android application for data display and the laptop. The digital controller is developed using the Quartus II V13.0 web edition software development tool on a Cyclone II EP2C35F672C6 Field Programmable Gate Array and the android application is developed using Kodular tool.
