Microcontroller based humidity and temperature remote
sensing

SYNOPSIS: At present, labor-saving and water-saving technology
is a key issue in irrigation. A
wireless solution for intelligent field irrigation system ,based
on Zigbee technology was
proposed in this paper. Instead of conventional wired
connection, the wireless design
made the system easy installation and maintenance. The hardware
architecture and
software algorithm of wireless sensor/actuator node and portable
controller, acting as
the end device and coordinator in Zigbee wireless sensor network
respectively, were
elaborated in detail. The performance of the whole system was
evaluated in the end.
The long-time smooth and proper running of the system in the
field proved its high
reliability and practicability. As an eplorative application of
wireless sensor network in
irrigation management, this paper offered a methodology to
establish large scale remote
intelligent irrigation system.
!eople now are working actively at intelligent irrigation
systems because their
advantages of labor-saving and water saving. "ireless
technology, known for its easy
installation and maintenance, is thought preponderant to develop
automatic irrigation
network and becoming a hot research.
The development, testing, and use of an integrated distributed
wireless sensor
network #"$%& that utili'es 'igbee technology are presented
in this paper for sensor-
based variable rate irrigation systems. The "$% eliminates the
need to hard wire
sensor stations across the field and reduces installation and
maintenance costs. The
"$% uses an zigbee network, i.e., a mobile wireless network.
(ompared with a
wireless local area network #")A%&,zigbee networks have
advantages for agricultural
applications, because the mobility and self configuration are
more suitable for a
distributed sensor network in fields. The ob*ective of this
paper is to report the design,
construction, and testing of a distributed in-field "$%, a
remote motor valve control, and
