Controlled System

Description

In regard to the software, device function based on the flow rate of air which is controlled by differential pressure between inside and outside of the helmet.

Using two BMP280 sensors connected to Arduino to collect the pressure data.

According to CDC requirements, the differential threshold should be 2.5Pa.

If the differential pressure < 2.5Pa, the motor driver speed up the fan to exhaust air to outside that create more negative environment in the helmet
