I teach middle school and I need to track when my students are going and coming back from the bathroom. They are disrupting class and they are falling behind. It's gotten out of hand and it's not like I can tell them they can't go. But if I can document the abuse, maybe I/we can improve their grades.
I'd like to build something I can put in the classroom that they can sign out and when they come back, they sign back in on. Then I have a record for the parents and admin so we can formally address this.
Can anyone help me with such a project? I'll be using the Nano (because I bought five of them) so the teachers in my team all can monitor the students in their classes too.
Parameters is a six digit ID which is their student ID, and some way for them to sign out and in. A datalogger. And if possible, an app for their phones.
Interesting project. A few things that will help us help you is how many students in total? Do they all have phones? You could use the browser and eliminate the need for an app. Do the students have a badge, preferably with a RFID built in?
Sorry for not getting back earlier. We're testing and doing holiday stuff.
I have 150 kids total that I teach. Up to 35 kids in a class.
The kids have a phone but they can't use them during school hours.
The IDs we have don't have RFID but we can add a sticker to the IDs and hope they don't peel them off. The kids have a five-digit Alpha Number (example: 1wqbt) to track their grades so I can use that as an identifier.
There are a lot of ways depending on what you have available and what you are willing to write. Check this link, it should give you some ideas: Overview | Using Web NFC | Adafruit Learning System A lot of this was done for smartphones such as Android but there are others that now support it.
I am assuming the badges are laminated plastic, next badge season you can embed RFiD stickers if you want. Let us know how you make out.
