To enhance efficiency, safety, and reliability (correct)

Which statement best describes the role of sensors in automation?

Sensors are used for fatigue management in automation

Sensors collect data for informed decisions in automated systems (correct)

Sensors have no role in automation

Sensors only measure human errors

Why is precision particularly important in industries like aerospace and medical devices?

Because precision increases manual labor

Because precision is not crucial in these industries
