INTRODUCTION
Advanced remote monitoring system (ARMS) is a device loaded with multiple features that provides the access of device parameters anywhere anytime. The advanced remote monitoring system reads data from its interfacing device, stores it and upload it on the server via GSM/GPRS on user define timestamp. It reads the data from any digital device through RS232 or RS485 (Modbus-RTU) and stores & uploads the same after user defined interval. The advanced remote monitoring system incorporates 32bit processor based state-of-art technology, Sigma Delta type power supply incorporated with EMI-RFI filter & spike suppressor and inbuilt opto isolation of signals & I/Os makes it a reliable product.
Data sending Communication without PC/PLC/SCADA makes this system very useful
& economic. Advanced remote monitoring system is robust in nature to withstand harsh environmental conditions. It can operate reliably over a wide temperature range and also in humid weather. The advanced remote monitoring system incorporates 32bit processor based state-of-art technology, Sigma Delta type power supply incorporated with EMI-RFI filter & spike suppressor and inbuilt opto isolation of signals & I/Os makes it a reliable product.

Power Supply
Internal power supply of data logger is switch mode power supply (SMPS). 750mA fuse is provided for AC power supply.
The rated AC supply is 90 V to 270 V AC 50 Hz.
Before connecting power to the data logger, ensure that the input voltage is within specified range.
When the instrument is switched „ON‟, the display will show test cycle and then software revision details for data logger.

1. Data transmission is an essential resource for different market sectors. Economic development and technological advance are creating the need for supervision and monitoring, and real-time information which is a determining factor in gaining new clients, managing resources and controlling the operation is becoming part of the strategy to survive in the market [1].
Systems in the SCADA model (Supervisory Control and Data Acquisition) enable this kind of control via data acquisition, remote and/or automatic transmission and actuation [2].
There is an increasing use of renewable energies such as wind generation.
Conscientious countries are seeking to reduce CO2 emissions; the energy revolution may become a reality [3], increasing our day-to-day comfort and using clean energies to lower consumption. In order to enable the use of renewable energy systems, we need these systems to be self-sufficient or to require minimal maintenance. Remote monitoring systems do this for instance, by providing distant management of one or more wind generation units. A great advantage already due to remote monitoring is to reduce unnecessary visits by maintenance staff. Currently different technologies are used for remote monitoring but for many the use of the air communication channel is still a paradigm [4].
This article is the result of a study on wireless data transmission for remote monitoring of variables. A system that simulates the functioning of a wind turbine was used and two variables were transmitted. One of them is the tower vibration sensor signal, and the other the brake pad wear signal, since the wind turbine being studied has a disc brake which wears down these pads. The study below can be used as a reference for several applications that require data transmission using the wireless system. An example of this is pollutant emission monitoring applications, river stages (floods), flood alerts (reservoir levels), watershed control, reservoir monitoring and landslide warnings.
It can also be used for agricultural purposes, such as to obtain the weather forecast at remote sites. Also, irrigation systems can be controlled remotely in agriculture [5], 2. GSM/GPRS Systems
The GSM (Global System for Mobile Communications) is the second generation digital standard developed in Europe and used in most of the world [7].
It was initially developed for the 900 MHz wavelength and a version was later adapted for the 1800 and 1900 MHz wavelengths. One of the purposes of telecommunications systems standardization was to ensure that the user would have the service available

in any part of Europe. (Paragraph One, definition). The terminals consist of a transceptor and SIM (Subscriber Identity Module) Card. Without the SIM Card the mobile station cannot receive or make calls, since it is not associated with any user.
The SIM Card is a small chip that is used to store user data and their authentication code. The SIM Card can be disconnected from a transceptor and connected to another by the user himself, and it can also be used in any other GSM cell phone, since the data are stored on the chip. It is the SIM Card that provides the identity of the mobile unit, and the mobile terminal only operates when the SIM Card and transceptor are connected. The GSM standard is most used worldwide, since it has several technological innovations, such as international roaming among the countries of Europe, increased security (since the user authentication is performed at the terminal) and it has an open architecture (combination of equipment from different manufacturers). Generation second and a half These are cell systems that offer data services in packets without the need for a permanent connection [8].
It is an intermediate step to the third generation. The main systems are GPRS (General Packet Radio Services) and EDGE (Enhanced Data Rates Services) and HSCSD (High Speed Circuit Switched Data). GPRS (General Packet Radio Services) This is a basic service for GSM, which improves and simplifies access to data networks and transfers data packets between the mobile station and the data network [9].
GPRS solves the following problems: ™
Transfer of the data in packets; ™
Direct interconnection with IP networks;
Greater flows (dozens of kbps); ™
Low access time (< 1 s); ™
Rating directed at the data.
In order to use the GPRS, the users basically require: ™ a mobile telephone system or a terminal that can support GPRS; ™ a subscription to a mobile telephony system that can support GPRS; ™ have a licensed GPRS; ™ knowledge on how to send and receive information by GPRS using a telephone, including hardware and software configurations, which require a customer service system; ™ a destination to which to send or place to receive information through GPRS. The main characteristic of GPRS is to establish a data connection without the need to establish a phone circuit, which allows charging for use, not for time of connection, and the service is thus always available to the user. GPRS implementation requires small modifications of the installed structure, making it easier for GSM operators to adopt: ™ It is standardized to transport data defined by IP and x.25 protocols. ™ The Serving GPRS Support Node

(SGSN) performs the logical connection of the mobile users when they go from the area covered by one cell to another (handover). ™ Gateway GPRS Support Node (GGSN) allows internet connection. When a GPRS terminal is energized, it will be recognized by the network similarly to what occurs with a GSM voice terminal. Then a logical linkage is created between the terminal and the Serving GPRS Support Node (SGSN). An IP address must then be obtained establishing a connection in the GPRS. The IP address is supplied by the mobile operator. At this point the GPRS terminal is ready to send and receive packets. Classes of Terminals: ™ Class A Terminals that can process voice and data at the same time ™ Class B Terminals that can process voice and data, but not at the same time ™ Class C Terminals that can only process data The GPRS terminal can be used directly for access to data or to the internet using WAP (Wireless Application Protocol), or it can be connected to another
