Safe in school – hardware

Design and implement a stand alone device checking and track pupils attendance in special school with RFID scan reader

A unique device designed for tracking and synchronizing pupils attendance in special school,
the device is managed by the ESP32 proccessor which control the work flow, and provided with built-in WIFI which can connect to the schools internet site

it uses the WIFI to connect to the schools server on the internet, then when a pupil gets closer the RFID scanner scans the tag and send it to the server,
where that data is encoded and synchronized into the pupils database.

the device can detect a tag in 3-8 meters radius, and it includes a real-time clock to allow adding the feature of limiting the device functionality to the study hours to save power .

The device power is managed by the power management unit, which includes a Solar panel, chargeable battery and two DCDC converters on to 12V and one to 5V,
the solar panel charges the battery and the battery powers the device, so no physical connection to the wall is needed.

The device schematic was designed using Cadence: OrCAD, tested and verified using Arduino environment and python scripts.
