DESIGNING A SENSING UNIT OF A SENSOR NODE

The main objective of tbis project is to design a sensing unit of a sensor node.
Sensor Node is a device tbat using sensors to gatber information and do analysis of
data gathered from where it being distributed. Distribution of a set of sensor nodes in
a particular area is called as sensor network. Sensing Unit is one of tbe basic
components in a sensor node and its design consideration is very important since it
served as the front-end of a particular sensor node. In tbis project, two sensors will be
used which are temperature sensor and humidity sensor to collect data. The
methodology of tbis project includes tbe collection of data from tbe sensors,
implementation on tbe microcontroller as tbe main brain system and the use of LCD
and LED to show and verify outputs. Laboratory experiments have been conducted to
test tbe sensors. The data collected tban been manipulated in tbe C Program for tbe
microcontroller to produce usable output which in LCD Display aod LED for the
binary readout. As a conclusion, tbe whole project is to design a complete prototype
of a typical sensing unit based on tbe constraints available.
