Real-time monitoring of sleep is the key to detecting sleep apnea. To solve this problem, an Internet of Things- (IoT-) based real-time sleep apnea monitoring system has been developed. It will allow the user to measure different indexes of sleep and will notify them through a mobile application when anything odd occurs. The system contains various sensors to measure the electrocardiogram (ECG), heart rate, pulse rate, skin response, and SpO2 of any person during the entire sleeping period. This research is very useful as it can measure the indexes of sleep without disturbing the person and can also show it in the mobile application simultaneously with the help of a Bluetooth module. The system has been developed in such a way that it can be used by every kind of person. Multiple analog sensors are used with the Arduino UNO to measure different parameters of the sleep factor. The system was examined and tested on different people’s bodies. To analyze and detect sleep apnea in real-time, the system monitors several people during the sleeping period. The results are displayed on the monitor of the Arduino boards and in the mobile application. The analysis of the achieved data can detect sleep apnea in some of the people that the system monitored, and it can also display the reason why sleep apnea happens. This research also analyzes the people who are not in the danger of sleeping problems by the achieved data. This paper will help everyone learn about sleep apnea and will help people detect it and take the necessary steps to prevent it.

In nowadays we need to stay connected. In most of the college’s, announcements are seen under the major problem. A universal announcement by speakers is usually deployed in most of the institutes, but there are cases when the announcement must be for specific classroom or for a specific person. There in case, such a universal system won't be helpful. Talking of colleges, the scenario in the classroom currently involves communicating facilities. The communication is generally using a student address system accessible from the control room only. This system removes a delay in case of emergency or even when an urgent communication is to be made. The proposed system aims to connect the communication between HODS or an authorized person of the department to the students or workstation, thereby ensuring good communication. We can achieve this using NRF24L01 Antenna Wireless Transceiver, Arduino NANA, Sound detection sensor module and speakers.
