The current IT market has been growing uninterruptedly, and with the spread of inteligente systems, the need for integration between devices arises. With that said, automation has achieved great focus. Historic buildings and constructions can be dated from earlier times, but these are not exempt from integration projects. Far from it, the integration of these buildings has been widely performed, but projects of this nature have specific difficulties. The main objective of this study was to understand the difficulties inherent in automation and IoT applications in projects carried out in buildings and historic constructions in the northern region of Brazil, as well as to carry out a brief analysis of technologies that can be used to overcome possible difficulties or to even facilitate the automation itself. For this, a method of data collection was used through bibliographic research in articles, scientific journals and materials on the internet. Through the study carried out, it was possible to confirm that the main difficulties in the application of automation in historic buildings comes from the historic heritage protection laws, and from the physical state of the construction which is, in many cases, degraded, which requires restoration and restructuring works to accommodate the technologies to be installed.

This product was developed with the objective of preventing accidents caused by carbon monoxide in indoor environments due to the absence of detection, monitoring and control devices. To solve this problem, a solution was developed consisting of: embedded systems for sensing and controlling the environment, a cloud server for processing the collected data, and a web environment, so that users can view the entire operation in real time. To prevent any lethal accidents, the entire operation is automated, with the help of advanced communication protocols (MQTT and Web Sockets), programming tools (C, C++, JavaScript, PHP and Node.js), and electronic devices and components. We emphasize that, once harmful levels of carbon monoxide are detected, an alert notification is sent via email to the person in charge and, consequently, control actions help to regularize the environment in order to guarantee the physical integrity of the human beings present on site. After the regularization of the environment, a notification of normalization is also sent to the person in charge, all in an automated way.
