In [18], a preliminary design on the development of WSN
for paddy rice cropping monitoring application in Malaysia
is introduced, standard measurement parameters sensors such
as ambient air temperature and humidity, soil pH and moisture
are integrated in all nodes, there are two directions the
data will go, which is first linked to server data based system
to be recorded and revealed on Internet web page and
real-time alert system using SMS system via GSM modem
to person in charge cell phone. In [19], a WSN based on Zigbee [20] and Internet is proposed for monitoring a
field-environment factors in an automatic manner and dynamic
transmitting the measured data to the farmer or
researchers; the main part of the network acquiring unit
mainly includes the sensors of temperature and moisture in
air and soil, CO2, and illumination.
