基于STM32沼液液位监控系统的设计

摘要

A scheme is proposed in this paper basing on STM32 microcontroI er to monitor the height of Iiquid surface in biogas sIurry.With the core of STM32F103VET6 microcontroI er,the system adopts uItrasonic Iiquid gauge as sensor,uses CDMA moduIe to communication with network.The system possesses some advantages such as high accuracy,Iow-power cost, great abiIity and so on.%沼气综合利用把沼气与农业生产活动直接联系起来，具有良好的经济效益和社会效益。介绍一种基于STM32处理器的沼液液位监控系统设计方案。以STM32F103VET6微控制器为核心，超声波液位计作液位传感器，采用CDMA模块进行3G网络通信。系统具有精度高、低功耗、能力强等特点。
