Abstract： There is a special group of people who are prone to sleep apnea when they are in a sleep state at night. Once sleep apnea occurs， it will pose a threat to human life. A system has been designed to address this issue， which can emit sound， light， and vibration alarm signals during the early stages of sleep asphyxia. By providing timely alarms， the system can awaken sleepers and solve health and safety hazards faced by special populations.
