【System Function】
-Signal measurement: Use ST displacement detection components (LIS3DH/LIS2DH12) to detect the displacement information (digital signal) of the sensor user, and transmit the information to the MCU through the SPI/I2C interface .
-Altitude measurement: Use ST atmospheric pressure detection components (LPS25H) to detect the user's altitude, and understand the user's up and down stairs (slope) status and calorie consumption.
-Ultraviolet measurement: Use ST ultraviolet sensor components (UVIS25) to detect the ultraviolet index of the user.
-Data calculation: Use ST low-power Cortex M0 to calculate the user's movement distance, calorie consumption, and speed calculation with the obtained raw data.
-Data display: The information obtained in the previous step can be displayed through LCM or NFC /Bluetooth NRG and mobile phone/NB connection display.
