Examples of physical mounting/enclosure for Gravity UART Infrared CO2 Sensor (SEN0220 aka MH-Z16)

I am wondering if there are recommendations or application notes regarding physical mounting and housing for measuring a gas flow in an enclosed system (as opposed to ambient measurement where it can hang freely in air).  

Is there a recommended range of air flow (air speed) across the sensor, and would a high velocity possibly disturb the measurement?

For my purpose I want to measure the CO2 concentration in exhaled breath, and am just looking for any examples such as pictures or diagram of how others have mounted it and best way to direct the gas flow over the sensor.
