Most of Sensor Networks (SN) or sensor systems have a main target. This target is theinstantaneous collecting of data or sensors readings every second (or fraction of seconds) and transferring / sendingthis data to a main computer or network server. The techniques used to collect and transfer network data to the main computer plays a vital role in goodness / robustness of that monitoring system. This research aims to design and implement a mobile unit to collect data that are read from a collection of sensors within an environmental monitoring system. A new concept of portable data acquisition unit and how it saves the sensors readings that are collected from network nodes is explained in details in this research. In this research, the technique for collecting and storing the sensors data is presented by using modern memory card (microSD). Through the use of this storage media the sensors or network nodes can store their data from any location and at any time for processing and analyzing targets. Furthermore, we illustrate how to design a portable or mobile network node or unit to perform the required measurements of temperature (using three LM35 sensors) and air quality measurements (using MQ135 sensor). This portable unit containing a Data Logger can work independently and collect sensors readings and store them on a microSD memory card quickly and efficiently.
