Abstract

 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. Keywords: Data acquisition system, Mbed NXP LPC1768, LabVIEW, Human machine interface, manual, automatic.

Abstract

Many physical phenomena and processes in the environment must be monitored. This problem can be solved with an ad-hoc wireless sensor network (WSN), which consists of a number of small and self-power sensing devices (nodes) that are connected with each other using effective wireless networks. This paper reports development of an embedded wireless sensor network (WSN) prototype for environmental parameters monitoring. The network itself consists of a coordinator or data gateway which wirelessly collect temperature and humidity data over several sensor nodes. Each sensor node is developed from an arduino based microcontroller, Xbee wireless module based on Zigbee/IEEE 802.15.4 standards, and temperature and humidity sensor devices. In the prototype system, both temperature and humidity sensors are calibrated with accurate instruments to obtain precise measurements. Its communication functionality is also tested in various network topologies. The battery lifetime is calculated to predict the energy consumption. The testing results show that the system works well in terms of its functionality.
