The system collects the user's sleep data, including the user's heart rate, average bedtime, average number of bedtimes and other data, and sorts out a sleep monitoring report. Multiple sensors record the sleep data of each user and upload it to the cloud to analyse the sleep status of each user. You can use the tablet to view the cardiovascular health index, breathing disorder index, sleep staging, accurate heart rate changes and other data of each user in real time. The system can use the data to sort out trend charts to accurately analyse the user's physical condition.
