Abstract

A gaseous-fluid environmental sensor having a gaseous-fluid flow system that defines a flow path coupling an intake port to an exhaust port. The gaseous-fluid flow system includes a blower and a flow sensor. The blower includes a motor and the flow sensor senses a flow-related parameter. The gaseous-fluid environmental sensor further includes a battery, an electrical sensor sensing an electrical power-related parameter, and a controller electrically coupled to the electrical sensor, the flow sensor, and the motor. The controller is configured to generate a composite drive waveform having a first component based on the sensed flow-related parameter and a second component based on the sensed electrical power-related parameter. The controller is further configured to drive the motor using the composite drive waveform. Also disclosed is a method of controlling the gaseous-fluid environmental sensor.
