description: The aim of the graduate l work is to develop a microcontroller device for monitoring the magnetic field based on the LSM303AGR magnetic field sensor related to microelectromechanical systems (MEMS). In the course of the work, the following tasks were set: â¢ Development of a structural diagram of the device; â¢ Selection of element base; â¢ Development of a schematic diagram of the device; â¢ PCB design. In the course of the work, microelectromechanical systems and the history of MEMS were considered. A review of various types of magnetic field sensors were considered., their principle of operation and key features were considered. In the process, a structural and circuit diagram of the device was developed. Element base selection was also carried out. In the course of this work, we studied the features and main characteristics of the STM32L4 microcontroller, examined the low power consumption modes of the microcontroller. The characteristics of the LSM303AGR magnetic field sensor were studied. Also, in the course of work, a serial I2C communication interface was considered for communication between the microcontroller and the sensor. Modulation and coding were studied in LoRa wireless data technology. As a result of the work, a model of the printed circuit board of the magnetic field sensor with a track width of 0.2 mm for signal circuits and 0.3 mm for power supply circuits was designed. The printed circuit board is made on a 2-layer fiberglass with dimensions of 33 Ã 22 mm2. In the process, work was mastered in the cloud environment of computer-aided design of electronics EasyEda. The features of PCB tracing were studied.
