Abstract:

This project deals with the design and development of hardware and software for industrial data logger system. Data acquisition is the process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems typically convert analog waveforms into digital values for processing.

Present world mostly is being controlled by internet. Previously internet is limited to only computers but because of the advancement in technology especially in mobile communication, now internet is completely being accessed by latest phones like Smart phones 

The aim of this project is to monitor the parameters of industry from anywhere in the world from PC or phones through internet. 

In this project we will create an application to monitor the industry parameters like monitoring temperature, light intensity, etc. Whenever we open this application it gives the current status of industry. At industry side we have Ethernet module, micro controller, temperature sensor, LDR sensor and humidity. This micro controller will keep updating these parameters data on webpage. We can check these values from anywhere on our Smart phones or on PC by opening this webpage. The communication between internet and micro controller is established using Ethernet module and the controller is used in this project is ARM7 based LPC2148 32 bit controller. 

The NXP (founded by Philips) LPC2148 is an ARM7TDMI-S based high-performance 32-bit RISC Microcontroller with Thumb extensions 512KB on-chip Flash ROM with In-System Programming (ISP) and In-Application Programming (IAP), 32KB RAM, Vectored Interrupt Controller, Two 10bit ADCs with 14 channels, USB 2.0 Full Speed Device Controller, Two UARTs, Two I2C serial interfaces, Two SPI serial interfaces Two 32-bit timers, Watchdog Timer, PWM unit, Real Time Clock with optional battery backup, Brown out detect circuit General purpose I/O pins.
