Design of Liquid Level Monitoring System Based on STM32 and NB-IoT
In daily life,there are diverse application requirements for accurate liquid level measurement.This paper designs a liquid level monitoring system based on STM32 microcontroller and NB-IoT technology.The system is aimed at achieving precise measurement of liquid level,local abnormal response,and remote cloud monitoring.By using a liquid level sensor to collect real-time data on liquid level,the system can complete local automatic alarm and response to liquid level abnormalities with the help of the STM32 microcontroller.Meanwhile,leveraging the low power consumption,wide coverage,and strong connectivity features of the NB-IoT module,the system realizes remote monitoring and management.The experimental verification results show that the system performs well.It can accurately collect liquid level data,the local respond is normal,and cloud monitoring is reliable,meeting the application needs.
