The goal of surveillance is to gather meteorological data, to aggregate assessment. Keywords: GPRS, GSM, EDGE, GPS ,CAN, protocol ,web, at-command 1km), 1. INTRODUCTION Currently in Vietnam, Weather monitoring is still rudimentary, for Convenience and Accuracy, there should be a system which can collect the data automatically. Our system consists of three main parts: data acquisition we arranged with the network communication system CAN. CAN network is transmitted to 1km away and eliminate possible interference. In the further stage, we allocate the communications GSM, GPRS, EDGE, the communication can be anywhere with electromagnetic waves it is convenient to be circuits, data circuits and Website. located in remote places. Station 1 Station 2 CAN GSM/GPRS/EDGE Station Server 2. OVERVIEW OF SYSTEM Website . Introduction to collect rain sensor In fact, the rain sensor measures the Station n volume of rainwater, then interpolates to the GSM/GPRS/EDGE Station ( have model GSM/GPRS/EDGE ) amount of rain. Figure 2 is a rain sensor manufactured by us: Fig 1. System network The design system depend on the distance near the station layout and coordinate the communications. In the wireless environment and can communicate at close range (under Trang 75 Science & Technology Development, Vol 15, 2012 Fig 3. The principle of the sensor flip bucket . System Introduction The diagram below describes an weather (a) Old sensor monitoring and control system that we .
