The objective of this project is to design a security alarm system that can monitor an industry with 4 different sensors. The project depends upon AT89S52 micro controller. This micro controller provides all the functionality. A maximum of 4 sensors can be connected to the buzzer. A power supply voltage of +5 V DC is applied for each sensor. When sensor is activated then we get sound through siren. The uniqness of this project is it sends a caution message to four mobile numbers by using GSM modem. This numbers can be stored in EEPROM. This 4 mobile numbers can changed at any time by using 4*3 keypad. This project uses regulated 5V, 750mA power supply.7805 three terminal voltage regulators is used for voltage regulation. Bridge wave rectifier is used to rectify the A.C output of secondary of 230/18V step-down transformer. Index Terms- SMS Alert System using GSM Modem, IR sensor, LDR sensor I. INTRODUCTION Industrial safety and security includes security and health of employees in a company venture, supervisors develop a focus on safety that include components such as: management leadership as well as dedication, security development and so on. This paper presents the Security Integrated System Based on Wireless Access Protocol for Industrial Applications with SMS Alert System using GSM Modem. The objective of this project is to design a security alarm system that can monitor an industry with 4 different sensors. When the sensor is activated then we get sound through siren. The uniqness of this project is it sends a caution message to four mobile numbers by using GSM modem. This numbers can be stored in EEPROM. This 4 mobile numbers can changed at any time by using 4*3 keypad. The rest of the paper discussed as follows. The below section2 describes about some previous security systems Section3 describes about overview of proposed system and various blocks present in proposed system. Section4 describes about working and results of proposed system. Section5 concludes the paper with an idea to implement the same as a real time project. II. AN OVERVIEW OF SOME PREVIOUS IRRIGATION SYSTEM GSM Based Industrial Security System [1] presents user friendly and low cost home and industrial automation and security systems. It includes home automation design with wireless networks. A simple system to improve the standards is developed. It is a real time monitor able system developed with simple hardware which simplifies the possibility of error free security system. This system easily implements with maximum reliability and the high security with low cost. Wireless Home and Industrial Automation Security System Using GSM [2] presents mobile controlled user friendly and low cost home and industrial automation and security systems.. A simple system to improve the standards is developed. It is a real-time monitor able and remote controlled system developed with simple hardware which simplifies the possibility of error free security system. The main control program is developed by using embedded C language and converted to exe file by using Keil package. This program includes interaction between all hardwares connected in microcontroller and sends appropriate signal to the User through GSM. System.. Security for Industrial Communication Systems [3] presents Information-system security for industrial automation and communication systems has only very recently emerged as a new field in academic and industrial research. The importance of this research field will grow in the near future, because security considerations and mechanisms are increasingly required as a part of standards-based best practices and because enterprises recognize the business case
