You can use the air-pressure module to measure the absolute air pressure. Please note that it is the relative air pressure that is given in, for example, weather reports or other media. The relative air pressure always refers to sea-level. This module was developed to automatically compensate
for the relatively high dependency of the oxygen saturation in the water
on air pressure. If the air pressure is not taken into consideration, it
is quite feasible that errors in measurement can result of around 5% in the
figure for oxygen saturation.
Save yourself more serious damage.
