Abstract Aiming at the low-rate and short-distance
communication in existing temperature and humidity monitoring
system this paper designs a remote monitoring system based on
3G and technology This system consists of data
acquisition module and data remote transmission module
Atmega128 is used to be as a master control chip of data
acquisition module which realizes the data acquisition and
pretreatment and the collected data is transmitted to the host
node by the low-power wireless transmission module NRF905
which is installed on slave nodes and then the converged data is
transmitted to by 3G module The system can realize
remote monitoring centralized management and so on The
experimental results show that the system has the advantages
of
low installation cost low consumption high sensitivity high
accuracy long-munication and high rate etc

I INTRODUCTION
With the rapid development works and
communication technologies remote monitoring technology in
the data acquisition and analysis has been widely used [1-7]
The traditional data acquisition system generally uses the
computer PC slave node mode Slave nodes use a wired
connection so that wirin g tedious poor scalability Especially
for the vast space environment if a wired connection is used
the cost and power consumption is high In addition in t
