CHAPTER 4
RESULTS AND ANALYSIS
Overall, this chapter discussed the result attained from the system
development and analysis for each result. The result was obtained from both wired
and wireless communication. Result obtained from these system output measured
using oscilloscope and the data transmitted can be read using USART terminal.
Some of the result was captured using ISIS Proteus software. Wave captured from
this software was similar with the data captured by the oscilloscope. To obtain the
result, this software read the data from RS232 connector that connected from the
microcontroller board to the computer. The results have been analyzed to guarantee
data collected at the receiver node is similar as transmitted at the transmitting node.
4.1 Hardware Development
As mentioned in chapter 3, water sensor system design process divided onto
three phases which are the electronic design or the hardware development, sensor
node programming or the software development and final phase, the overall system
testing development. This system successfully completed the first phase of the
system development which is the development of electronics components.
