Gas sensor devices and housings
Devices, assemblies, and associated methods are provided for gas sensors. An example device for use with a gas sensor includes a buoyant housing that receives the gas sensor therein, an inlet opening defined by the housing, a pump positioned within the housing, and an outlet opening. The pump is in fluid communication with the inlet opening and the gas sensor in an instance in which the gas sensor is received by the housing. The pump is configured to cause gas received by the inlet opening to be directed to the gas sensor for evaluation, and the outlet opening is configured to discharge gas exiting the gas sensor from the buoyant housing. In an operational condition in which the device is placed in a fluid, the buoyant housing is configured such that at least a portion of the buoyant housing floats above a surface of the fluid.

4. The device according to claim 2 , wherein the top cover further comprises a latch configured to, in the closed position, engage the bottom cover.
5. The device according to claim 2 , wherein the inlet opening and the outlet opening are each defined by the top cover.
6. The device according to claim 2 , further comprising one or more housing sealing membranes configured to, in the closed position, substantially seal the buoyant housing from the ingress of fluid such that the buoyant housing is substantially watertight.
7. The device according to claim 2 , wherein the bottom cover further defines a pair of engagement elements configured to receive a strap attached thereto.
8. The device according to claim 2 , wherein the top cover further defines one or more input features configured to:
receive an input from an operator of the device; and
actuate corresponding buttons of the gas sensor in an instance in which the gas sensor is received by the housing.
9. The device according to claim 1 , further comprising a gas block supported by the buoyant housing configured to direct gas between the inlet opening and the pump and between the pump and the gas sensor.
10. The device according to claim 9 , wherein the gas block defines:
a first channel extending between the inlet opening and the pump; and
a second channel extending between the pump and the gas sensor.
11. The device according to claim 1 , further comprising an outlet filter disposed on an inner surface of the top cover at the outlet opening.
12. The device according to claim 1 , further comprising an inlet filter defined by the top cover at the inlet opening.
13. The device according to claim 1 , further comprising a power source positioned within the housing and in electrical communication with at least the pump.
14. A gas sensing assembly comprising:
a gas sensor;
a buoyant housing, wherein the gas sensor is positioned within the buoyant housing;
an inlet opening defined by the housing;
a pump positioned within the housing, wherein the pump is in fluid communication with:
the inlet opening; and
the gas sensor, wherein the pump is configured to cause gas received by the inlet opening to be directed to the gas sensor for evaluation; and
an outlet opening defined by the housing, wherein the outlet opening is configured to discharge gas exiting the gas sensor from the buoyant housing,
wherein, in an operational condition in which the device is placed in a fluid, the buoyant housing is configured such that at least a portion of the buoyant housing floats above a surface of the fluid.
15. The assembly according to claim 14 , wherein the buoyant housing defines a bottom cover and a top cover movably attached to the bottom cover, wherein the top cover is movable between a closed position in engagement with the bottom cover and an open position at which selective access to the interior of the buoyant housing is provided.
16. The assembly according to claim 15 , wherein the inlet opening and the outlet opening are each defined by the top cover.
17. The assembly according to claim 15 , further comprising one or more housing sealing membranes configured to, in the closed position, substantially seal the buoyant housing from the ingress of fluid such that the buoyant housing is substantially watertight.
18. The assembly according to claim 15 , wherein the top cover further defines one or more input features configured to:
receive an input from an operator of the device; and
actuate corresponding buttons of the gas sensor.
19. The assembly according to claim 15 , further comprising:
an outlet filter disposed on an inner surface of the top cover at the outlet opening; and
an inlet filter defined by the top cover at the inlet opening.
20. A method of assembling a device for use with a gas sensor, the method comprising:
providing a buoyant housing configured to receive the gas sensor therein;
defining an inlet opening in the housing;
positioning a pump within the housing, wherein the pump is in fluid communication with:
the inlet opening; and,
the gas sensor in an instance in which the gas sensor is received by the housing, wherein the pump is configured to cause gas received by the inlet opening to be directed to the gas sensor for evaluation; and
defining an outlet opening in the housing, wherein the outlet opening is configured to discharge gas exiting the gas sensor from the buoyant housing,
wherein, in an operational condition in which the device is placed in a fluid, the buoyant housing is configured such that at least a portion of the buoyant housing floats above a surface of the fluid.
