The growing demand for new technological solutions in automobiles, often to replace mechanical with electromechanical solutions, seeks better system controls to improve fuel economy and reduce pollutant emissions, while also improving the comfort and safety of vehicle users. With the recent advances in microelectronics, many sensors are being used in unexpected applications, an example of which is the Hall Effect Sensor, which is increasingly used in vehicles due to its ease of application. The contribution of this work is the development of a temperature control valve (TCV) that replaces the thermostatic valve with a more accurate temperature control system, using a Hall Effect Sensor to control the flow of the engine cooling fluid. The implementation of the Hall Effect Sensor enables new functionality to the TCV, which previously had just two operative states (On and Off). In this way, it is possible to improve the temperature control of the combustion engine.
