Proof of concept modular scent station to deliver 24 individual scents to participants, preprogrammed or manual
Based on open source hardware and software, this project allows for an operator to deliver 24 unique scents to participants. We used an Arduino Mega for the controller and designed a board controlling power and solenoids to plug into the standard pinout of the Mega. For the mechanical 24 solenoids were pressurized and when fired injected scent into a large mixing tube which then turned on a fan to move the scented air to the participants. Each unit can be attached to two other units in a master/slave configuration.
First testing of the unit in a public setting was successful and follow on production of unit will be in 3rd quarter of 2016.
