Hi @BSTRobin ! Thank you for the attention to my question. Basically, I want to develop a weather station and air pressure is one of the quantities to be measured. I'm a weather station developer, not a meteorologist. The uses are therefore varied. About gases : the weather station can be used in the nearby of volcanoes. In case of volcanic activity, many gases can emanate. Mainly carbon dioxide but also e.g. sulfur dioxide, sulfur monoxide, hydrogen sulphide, etc. Can exposure to these gases affect the sensor ? About shocks : the station can be used, for example, in civil engineereing application like a demolition site (old building to be destroyed) where users need to know the wind and speed direction in order to manage dust. In such a situation, at the time of the explosion, the shock wave can reach the sensor and one have to be sure that it will not be damaged. Thank you very much for your help. Best regards
