I need to create a system from a door sensor (for example, a closet door), where I get the information that the door is open or closed and how many doors are available for use. It will also require that this system be interconnected with an application and it will send sms codes with random passwords to open these encoded ports.

Dear Sir, I am an embedded systems expert with more than 15 years of experience in firmware development and Product Engineering. I have checked the details of your work. What you need is a complete systems along with Hardware/Software Solution. This can be realized with small Wireless sensors (MCU+RF Chip) to detect the door position and send its status to a central server/hub. That hub can have BLE (Bluetooth) or WiFi as the uplink. I recommend WIFI as it can further be integrated with the cloud. The application hosted by the hub (which can be accessed over cloud/internet or locally over LAN in case of wifi) would be accessible via smart phone or a desktop PC. The hub shall then send sms to respective users. So I recommend a GSM/GPRS modem instead of WiFi or BLE as the uplink at hub. This would push the data to some remove server and also generate sms to mobile numbers. Regards Ch
