ABSTRACT:
The present invention concerns a method for detecting the start of a dive for implementation in a portable electronic device (1) of the diving computer type. More specifically, the method is for implementation in a device of this type having at least a first operating mode and a second operating mode, called the dive mode. This device includes a pressure sensor (5) for measuring the ambient pressure value (P) and electronic circuits (2) for processing the pressure measurement results including a time base (4) and at least one memory zone (7, 8).The detection method according to the present invention more particularly proposes making correction to certain measured pressure values before storing them as reference pressure values (Pref). Thus, the start of a dive can be detected with a high level of reliability solely on the basis of ambient pressure measurements.
