This document proposes a GSM-based industrial automation system that uses a PSoC microcontroller to monitor and control industrial devices via SMS commands sent from a mobile phone. Sensors detect process variables and relay switches control devices. The GSM modem provides wireless communication between the system and maintenance officers who can remotely monitor sensors and control machinery from anywhere using their mobile phones. This low-cost solution aims to reduce maintenance costs and optimize critical monitoring compared to existing wired, wireless, and RF-based systems.

2. ABSTRACT
 Monitoring is very important in Industries.
 Monitoring is done by sensor with most accuracy and
reliability.
 In industry, maintenance officer send an command to the
PSoC chip via GSM.
 PSoC decodes the commands and control the industrial
devices through relays.

3. OBJECTIVE
 To deliver an uninterrupted output.
 To reduce the maintenance cost and to optimize critical monitoring
system.
 To allow easy use of mobiles in order to control industrial
machineries simultaneously.
 To provide necessary data related to industry to a maintenance
officer located anywhere at any time.

4. EXISTING SYSTEM
 RF Based System
-short distance communication
 Wired technology
- Difficult to monitoring & long construction time
 Wireless technology
-High cost and high power consumption

5. PROPOSED SYSTEM
 We propound GSM BASED INDUSTRIAL
AUTOMATION SYSTEM.
 The design of Stand alone embedded system can monitor and
control various process, equipment and critical systems.
 The Systems are controlled by the mobile phone by sending
Commands via SMS.
 GSM modem provides the communication media between the
authority and the system.

7. HARDWARE NECESSITY
 PSoC Microcontroller
 GSM modem
 Sensors
 Relay

8. SOFTWARE NECESSITY
 Assembly language using C prototype
 TOOL: PSoC designer suite

9. PSoC MICROCONTROLLER
 It is an 8 bit microcontroller architecture.
 In PSoC we have an additional peripheral units such as
operational amplifier, filter, D/A & A/D Converters in an
in-built manner we get the chip in small size
 It reduce the power consumption.
 Automatic code writing for accessing all the peripherals
and it will operate at low voltage supply -1V.

10. GSM MODEM
 Global System for Mobile Communication (GSM) is a
wireless modem used for communicate computer with the
GSM network.
 It requires SIM(Subscriber Identity Module) to activate
communication with network.
 GSM needs AT commands to perform the operation such
as receive, send, delete, search, add SMS in a SIM.

11. RELAY
 Relay is an Electromechanical device mostly used in
industrial automation.
 It provide electronic to electrical interfacing.
 It is used to switch on or off electrical circuits.

12. SENSORS
 Sensors are sophisticated devices which is used to detect
and response to electrical or optical signal.
 The sensor converts the physical parameters in to a signal
which is to be measured electrically.
 Sensors are used in industrial process control,
measurement, monitoring and also used in aircraft,
medical products, automobiles etc.

13. APPLICATION
 This project can be implemented in Home Automation
System.
 Industrial Sensor processing and control.
 Remote operations in Industries.

14. ADVANTAGES
 Global range.
 Full flexibility to control the machineries.
 Low cost.
 Easy to maintain.

15. CONCLUSION
 The GSM network is used to help the user to control the
system from a distant area by sending secret code.
 Critical sensor monitoring by using wireless are the
challenges faced by the industries.
 By this method we can easily made an interact with the
device and the user.
