THE DEVELOPMENT OF MONITORING AND CONTROLLING SYSTEM OF FLUID LEVEL USING LABVIEW BASED ON MBED NXP LPC1768 MICROCONTROLLER

Based on retrieval and data processing need of an increasingly complex and varied, required for a device that can handle these needs, the computer-based system. The retrieval and processing of data to be read by computer must have a data acquisition system, one of them is a MBED NXP LPC1768 microcontroller. System monitoring and control of liquid levels use mbed NXP LPC1768 microcontroller as the data acquisition system and LabVIEW software as human machine interface (HMI). Data acquisition system between mbed NXP LPC1768 microcontroller using serial communication with the computer. Programming with LabVIEW software built with the blocks into a system program. The control and monitoring with LabVIEW microcontroller based can be implemented by serial communication with LabVIEW software that responds from sensor and equator can be monitoring and controlled in real time. The liquid level control was done in two ways: manually and automatically. two ways: manually and automatically. Automatic liquid level control is by setting the value to the desired level then it will work itself appliance reaches the set value.
