Many to Many Database
This website uses a many-to-many database linking different users to different topics. Each topic links to several sensor data points. This means any user can view the sensor data related to any topic that they have registered to their login.
Adding Topics
The website has a simple menu to link a topic to a user. These topics can also be assigned to multiple users.
Viewing linked topics
All topics linked to a user can be viewed on a table displaying all Topic IDs and Topic Names linked to a user.
Graphing Sensor Data
The website can also graph all sensor data linked to a topic with the capability to dynamically select data over the selected time range.
Data Display
When viewing the data graph shown above the most recent data collected for a topic is displayed below the graph for more accurate viewing of the recent data.
Data Usage
This data was planned to be used to monitor temperatures in a freezer. This data would then be monitored and if it rose above a set temperature it would send an email or phone message to the user linked to the topic to notify them of an issue. This threshold would have been editable for user convenience. The data collected was currently only formatted for temperature data but could be expanded to other sensor types by adding a sensor type linked to a topic. This would expand to capabilities of the website to monitoring many different information collected by users.
