STM32 Microcontroller Smart Bracelet Heart Rate Pedometer Temperature
Introduction The STM32F103C8T6 microcontroller core board circuit, ADXL345 sensor circuit, heart rate sensor circuit, temperature sensor, and LCD1602 circuit are combined. The ADXL345 gravity acceleration sensor detects the state of a person, calculating the number of steps walked, walking distance, and average speed. The heart rate sensor detects heart rate in real-time, while the temperature … Read more
