Sensor orientation in flow system recommendations from Sensirion
• Gravity pulls dust particles towards the bottom side of a gasflow channel, where it might accumulate over time. Whenever possible, place the sensor on the top side of the gasflow channel to avoid dust sedimentation into the sensor.
• Dust is heavier than the surrounding gasflow. You can use this higher momentum of inertia to your advantage: If the inlet to the sensor points against the direction of flow, dust will not be dragged into the sensor.
