A low-cost, low-power meteorological data monitoring terminal based on domestic microcontrollers was developed to address the operational requirements of local meteorological departments. The system incorporates a WIFI module for seamless internet connectivity, facilitating real-time access to meteorological information. Additionally, it integrates voice recognition and playback functionalities through a dedicated module for human-machine interaction, along with an OLED display for presenting pertinent data. The system enables real-time display, computation, and surveillance of meteorological data. Experimental results demonstrate that the system has effectively fulfilled its intended functions while maintaining an average power consumption of approximately 1.75mAh per hour, which has high practical value.
