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 offline voice recognition and playback functionalities through a dedicated module for human-machine interaction,along with an OLED display for presenting pertinent data.The system can display the meteorological data obtained by the network in real time,and can calculate and monitor the timestamp of the obtained data,so as to find the abnormal problems in the collection and transmission process of meteorological data in time and send out alarm signals. The experimental test results show that the system can accurately recognize a variety of timbres,and the voice and key operation functions are operating normally,and the power consumption is only about 1.75 mAh/h,which has high practical value.
