#Project Overview
Designed and developed a modular, universal HVAC control unit engineered to connect and interface with multi-vendor heating and cooling architectures. The controller collects local air quality, relative humidity, and temperatures, executing local optimization algorithms to adjust thermal outputs and control power consumption dynamically.
Equipped with optocoupled solid-state relays, the module shields core processing ICs from inductive voltage surges during compressor switching events, maintaining system uptime and reliability.
