Seat ventilation

Car seat ventilation refers to the ventilation function that can be achieved by designers using a fan to inject air into the seat, in which the air flows out from the small holes on the seat surface. This effectively improves the air circulation environment on the contact surface between the human body and the seat surface. The contact surface will be dry and comfortable even after sitting for a long time.

Based on MindMotion’s MM32SPIN023C microcontroller, the seat ventilation takes MM32SPIN023C as its main control.
