Prototype/Outcome

"I'm here" is a machine that produces air and is activated by human movements, such as entering a room. The machine stops producing wind breath- once the person notices the air and responds with a blow. This experience was created using multiple input and output modules. The PIR sensor can detect movement within approximately 10m of the sensor. The machine produced a puff of air with the help of a blower and a relay to control the air movement—a standard-sized servo due to the large blower, which needed an additional power source. The four AA batteries (total 6V) functioned satisfactorily. To stop the airflow, I utilized a flax sensor to detect it. The structure aimed to be built behind the wall, and only a few parts were revealed. The current prototype was made with a laser cut to simulate the wall, and the blow-in shell aimed to imitate the nest thermometer. The blow-out shell is designed to release air through a narrow opening rather than the current large, open mouth.
