IoT Embedded/Hardware Validation

ESP32 Smart HVAC Thermostat Controller

A microcontroller framework that interfaces residential 24V AC HVAC signaling with decoupled 3.3V DC logic. Optocoupler isolation, compressor anti-short-cycle protection, and state-interlock logic keep the system safe through unexpected power dropouts.
