This paper presents the construction of a prototype of a door and window monitoring system through an IoT platform. The objective was to design a system that reports to a server in the cloud the change of state, open or closed, of three doors and two windows of the equipment room of the data center. The changes of state are registered by the server and by means of a user interface the status of doors and windows is displayed online. The architecture of the system is based on a wireless sensor network integrated by a central node and five monitoring nodes. The monitoring nodes consist of a PyBoard card, two digital Hall effect sensors and a WiFi wireless interface. When detecting a change of state in doors and windows, the monitoring nodes notify it to the central node, and this transmits it to the server through a WiFi access point. When a door or window remains open for more than a configurable period of time, an SMS and WhatsApp message is sent to a mobile phone. The reach achieved in the WiFi transmission on the network was 47 meters with line of sight.
