What do wireless sensors worn by boaters do?

Wireless sensors worn by boaters are designed primarily to enhance safety on the water. When a boater falls overboard, these sensors can automatically detect the absence of the wearer and take critical actions, such as shutting off the engine or triggering an alarm. This feature is crucial for preventing accidents that could occur if a boat continues to operate while someone is in the water, thereby increasing the chances of a safe and swift rescue. Such technology significantly reduces the risks associated with falling overboard, making it a vital component of modern boating safety equipment.

The other functions listed, such as tracking location, measuring water temperature, or controlling speed, can be related to various boat technologies and instruments, but they do not encompass the primary purpose of wireless sensors, which focus on immediate safety measures when a boater is in distress.
