Turbulent Air Injector Controller | ECE443-Sp26

Spring 2026

Our system connects to an assortment of temperature, pressure and oxygen sensors, as well as up to 4 air injecting fans fitted into the firebox and chimney of the stove. The system can be controlled by two buttons to put the system in standby mode and adjust the power level of the fan algorithm, with visual feedback via LEDs. Our system features multiple serial interfaces to allow for communication with sensors and for booting the systems microcontroller. The microcontroller is booted over USB 2.0 and the microcontroller communicates with sensors over I2C and SPI. Because the connections to sensors and fans are partially outside of our system, we incorporated ESD protection on external connections. The system is powered via standard 120 or 240 VAC wall outlets to allow for ease of end use and versatility. One of our biggest challenges was designing the system's PCB. Combining all of our individual schematics and layouts into a single PCB required a lot of communication between team members and our advisor on our project partner team.
