Abstract

In this paper, our objective is to design, build, and verify a closed-loop environmental control system tailored for small-scale agriculture applications. This project aims to develop a low-cost, safety-critical embedded solution using the Nuvoton NUC140 microcontroller to automate temperature regulation. The goal was to mitigate crop yield losses caused by environmental fluctuations in a greenhouse. Our final implemented system successfully meets all design specifications, demonstrating robust temperature regulation through a PID control loop and ensuring hardware safety through galvanic isolation
