Enclosure for HP206C and HYT939

My team plans to attach a Raspberry Pi 4 to a drone and read temperature, humidity, pressure, and altitude using the already purchased HP206C and HYT939. I have not yet had a chance to look at these sensors in person but am looking into options regarding the enclosure of the Raspberry Pi, I2C shields, and the aforementioned sensors. I was wondering how much of the sensors need to be exposed to the outside air in order to take the readings, and how best to shield the sensors from potential damage such as dust and salinity.

i will recommend using gaskit filters like this
