| - | + | In 2022 it became mandatory for car companies to include an essential kit with assistance and safety sensors in their new models, but some models still lack essential sensors. However, according to DRPCIV, at the end of 2023, more than 81% of the cars in Romania had been used for more than 10 years [[msama#references|[1]]], so it is clear that most of them don't have the essential set of sensors. So this project aims to implement a system that makes the sensor integration in cars straightforward and easy to understand. | |

| - | MQTT is an OASIS standard messaging protocol for the Internet of Things (IoT). It is designed as an extremely lightweight publish/subscribe messaging transport which is ideal for connecting remote devices with a small code footprint and minimal network bandwidth. MQTT today is used in various industries, such as automotive, manufacturing, telecommunications, oil and gas, etc.[2]. For the project, the MQTT is used to easily transfer data from multiple sensors to a single broker that will process all the data provided by the sensors with some functionality additions. The MQTT communication visualization is presented as follows: | + | MQTT is an OASIS standard messaging protocol for the Internet of Things (IoT).
