工业生产高度发展的今天，自动化生产和无人值守技术日益完善，人力成本也逐渐增加，为了节约成本，很多生产领域引入智能控制，无人值守，将人员使用量降到最低，从而降低成本。水库、水文观测站、渔业养殖、水塔等都会观测水位，从而做出相应的应对措施。水位检测系统的研究就变得颇有意义。

基于GSM短信模块液位检测系统是一款用于检测水位的基于单片机控制的系统，当水位低于或高于某一水位，传感器感知到后，信息会经单片机处理后，单片机编辑相应的信息，通过无线短信平台，发送信息到手机上 。管理员收到短信后会做出相应的处理，避免了没事每刻都要检查水位的麻烦，解放了劳动力，降低了劳动量。GSM技术应用广泛，而且技术成熟稳定，GSM网络覆盖范围广，所以采用GSM短信模块作为通信模块，操作更为方便，传播距离更广阔。

本课题主要完水位检测，并将检测到的水位信息与设定值相比，水位超过设定的值时，它就会通过GSM模块利用GSM无线通信技术发短信到管理者的手机上等等！

-Today s highly developed industrial production, automated production technology has improved and unattended, labor costs also increased, in order to save costs, many areas of production introducing intelligent control, unattended, the amount of staff to a minimum, thereby reducing costs. Reservoirs, hydrological observation stations, fish farming, are observation towers and other water level, in order to make the appropriate response. Study level detection system becomes quite significant.

Based on GSM SMS module level detection system is a water-based system for the detection of single-chip control, when the water level is below or above a certain level, the sensor sensing that the information will be processed by the microcontroller, the microcontroller edit the appropriate information via wireless messaging platform, information is sent to the phone. After receiving the SMS Administrator will make the appropriate treatment, to avoid the fine should check the water level every momen
