Methods, apparatuses, and systems related to gas detection are provided. For example, an example apparatus for gas detection in an air duct component that receives a gas flow associated with gaseous substance is provided. The example apparatus includes a suspension connector component and a gas detection component. The suspension connector component includes a first end that is connected to a gas detection component so that the gas detection component is suspended within the air duct component. The gas detection component includes an asymmetrical outer housing so that the gas flow causes a randomized motion of the gas detection component within the air duct component.
