1. A gaseous-fluid environmental sensor, comprising:
- an inlet structure defining an inlet intake port to receive a gaseous fluid of an environmental space;
an outlet structure defining an outlet exhaust port to exhaust the gaseous fluid to the environmental space;
a gaseous-fluid flow system coupled to the inlet structure and the outlet structure, the gaseous-fluid flow system defining a flow path coupling the inlet intake port to the outlet exhaust port, the gaseous-fluid flow system includinga blower to move the gaseous fluid from the inlet intake port to the outlet exhaust port via the flow path, the blower having a blower intake port, a blower exhaust port, and a blower vent port, the blower intake port and the blower exhaust port further defining the flow path, the blower further having an air bearing, anda flow connector including a connector intake port and a connector exhaust port, the flow connector further including a chamber in fluid communication with the connector intake port and the connector exhaust port;
a flow sensor to sense a parameter relating to a flow of the gaseous fluid through the flow path and provide a signal based on the parameter; and
a controller coupled to the flow sensor and to control the blower based on the signal.

Abstract
A gaseous-fluid environmental sensor having a gaseous-fluid flow system. The gaseous-fluid flow system includes a blower to move the gaseous fluid from a inlet intake port to an outlet exhaust port via a flow path. The blower includes a motor, which can have a fluid dynamic bearing. The gaseous-fluid environmental sensor further includes a flow sensor to sense a parameter relating to a flow of the gaseous fluid through the flow path and provide a signal based on the parameter, and a controller coupled to the flow sensor. The controller controls the blower based on the signal.
