M-Duino, a PLC Arduino for control of parking area

Control your installations through Open Source Platforms

This project allows access control in a parking area, and automates the opening of the gate through a system which uses an RFID sensor connected to an industrial PLC by Industrial Shields.

Each user owns a unique card which contains the access data. A local database is stored in the SD memory card and it contains all the user access references. The system also monitors all the card reading process and allows the users to have knowledge about the process. 


Using this installation, each user will have a personalized card with a unique reference. All the references will be stored in an external server.

Each time that the database is modified, the industrial controller will update it on its memory card. When RFID sensor detects a registered reference, it activates the motor until the gate is fully open.


Our customer wants to control the access to the parking of his company using Open Source technology with a single controller Arduino that has the knowledge of all the registered users. It can also be remotely modified, acts on the gate and allows monitoring the full process.
