Wearable device for diving and detection method for diving

The invention provides a wearable device for diving and a detection method for diving, the wearable device can autonomously detect water out and water in of a user, diving data of the user is obtained according to the water out and water in state of the user, when the wearable device detects that the user is out of water, if the diving data meets the detection condition, timing is started, and the user can enter the diving state. When the water outlet duration of the user reaches the first preset duration, the wearable device detects the first oxyhemoglobin saturation of the user; the wearable device outputs a first detection result according to the first blood oxygen saturation degree of the user, and the first detection result comprises the lung injury level of the user. According to the method, the user can wear the wearable device during diving, the wearable device can automatically detect water out and water in of the user and obtain diving data of the user, after the user is out of water, timing can be conducted, the blood oxygen saturation degree of the user can be detected in time, lung injuries of the user can be detected in time, operation is easy and convenient, and efficiency is high.
