Abstract
We are going to show you a method that not only provides the best accuracy, but also saves us money and manpower. Each class's bell is rung by one of the staff members. The bell in colleges would sound automatically at the scheduled time if this design were to be implemented, taking over the responsibility of ringing the bell. It makes use of an actual Time Clock (DS3231) that monitors actual time. Furthermore, two additional bells that will sound in addition to the major bell will be used here. Wireless communication between the bells on the transmitting and receiving sides is made possible by the NodeMCU Wi-Fi module.We can utilise this automated bell ringing system for exams in addition to using it for lecture schedules.The bells used in schools and colleges nowadays are manually operated, which has accuracy issues. This automatic wireless bell encourages great accuracy.There is no danger of data leakage because data is entirely kept on the cloud. Some of the early techniques, including hand-ringing bells, are still in use today. More dependable and accurate systems have been introduced as technology has advanced.
