The Social distance mask project contains an Arduino-based distance sensor that triggers a tone to indicate distance of subject in front of wearer. As subjects get closer, the tone rises audibly. When subject reaches a close distance, liquid substance (sanitizer/water) squirts to sanitize / warn.
This mask is directly inspired by the virus and social distancing. Tone is an audible reminder of distance, and the mask is grotesque, squirting mechanism is an exaggerated reminder of transmission risk.
