Abstract：Liquid Level is one of the most common and important controlled variables in Industrial processes and receives widespread attention. Present liquid level control systems are almost based on traditional wired control, and have many disadvantages such as complex wiring, weak capability of resisting disturbance of signal, high cost, difficulty to Upgrade and maintain. This paper designs and implements a completed wireless liquid level control systeDesign and Implementation of Liquid Level Control System Based on Arduinom using oDesign and Implementation of Wireless Liquid Level Control System Based on Arduinopen source platforms of Arduino and Raspberry basDesign and Implementation of Wireless Liquid Level Control System Based on Arduino Using Internet of Thinged on technology of industrial control, RFID(RFID , radio frequency identification) and IoT (IoT, Internet of Thing). Designed wireless liquid level control system can solve the disadvantages of traditional wired control, adds functions of real time monitoring and abnormity warning, and has the advantages of low cost, multi-function, low power consumption, high accuracy, and excellent stability.
