What type of data do wireless sensors in health monitoring typically collect?

Wireless sensors in health monitoring systems are designed to collect vital signs, which include key physiological metrics such as heart rate, blood pressure, temperature, and respiratory rate. The primary function of these sensors is to provide real-time, continuous, and accurate measurements of a patient's health status, enabling healthcare providers to monitor conditions effectively and respond swiftly to any changes.

This real-time data collection is critical in various contexts, such as chronic disease management, post-operative care, and emergency health situations, where timely information can significantly impact patient outcomes.

In contrast, the options related to weather conditions, patient demographic information, and medical history do not align with the primary focus of wireless sensors in health monitoring. Weather conditions are irrelevant to individual health tracking, while demographic information and medical history pertain more to patient data management rather than the direct physiological metrics that sensors measure.
