Story

Phones, while good for communication, are such a distracting temptation when it comes to studying. This MEGR 371 IoT project device communicates from the hub to the students, giving them a reminder that they need to be studying. The hub controller can separately contact each student and then the student can confirm they are studying in return. Response times are recorded from each student.

Hub before sending "Study" message to students

Student has receieved study notice

The acknowledges both Students are studying

Each student's response times were then received from the student's response action and displayed as a graph below:
