UniPi controller board was used on demand of agricultural company residing in the South Moravia, the Czech Republic. This company came up with a task to ensure security of their estates used for plant growing.
Perimeter of their estate is approximately 750 meters of fence. To monitor any movements in the area there were put photoelectric sensors making a secured barrier all around the place. There were also put three motion sensors at strategic posts.
Whole security system is handled by two UniPi controller boards communicating with the server. After possible intrusion person in charge will be alerted immediately by both email and in the user interface.
This is one of the many examples how to use universal controller originally developed for PLC, HVAC and IoT technologies.
