| Abstract: | Barometric altimetry module is designed with MS5534C based on MEMS and AVR microcontroller.MS5534C is a digital pressure sensor produced by Intersema.There is three-wire synchronous serial interface between the microcontroller and sensor MS5534C for communication.Combining the measuring method of differential barometric altimetry in CAPS system with the module,which is applied in RSSI indoor positioning system based on mobile communication network.The measurement precision of absolute height of user is improved.The height of test point will be displayed on the LCD with the microcontroller.A good complementary effect will be formed for the indoor positioning system. |
