Design of a Low-Power Humidity and Temperature Collector Based on STM32

摘要

STM32 is a microcontroller based on CortexTM-M3 core; it plays an important role in the embedded control field. This chapter introduces a low-power humidity and temperature collector with SHT10 humidity and temperature sensors. This chapter introduces and implements the communication time sequence of SHT10. A calibration text proves that the system can measure temperature and humidity correctly. It is demonstrated by experiments that this low-power collector can collect data for 30 days and satisfy the design index; besides, the principle of low power can be used in other embedded control field.
