Project#1
INDUSTRIAL AUTOMATION USING CAN PROTOCOL (MOTOR SPEED CONTROL
BASED ON TEMPERATURE)
Tool
: Keil, ARM (LPC2148)
Language
: Embedded C
Description
This project is designed to control the DC motor based on the temperature changes using CAN
protocol implementation. This Project deals with the Control of DC Motor based upon the temperature
changes that occur in a process in Industry. The LM35 series are precision integrated-circuit temperature
sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The
Temperature changes are measured by the ADC and transmitted to the other node using the CAN Bus and
the data is received at the other node based upon the data received the speed of the DC motor is Regulated
using the PWM (pulse width Modulation) Technique. This PWM is achieved by on Chip Timers.
Contribution

UART programming to set the motor speed.

PWM Wave is generated to run the motor.

SPI programming to interface microcontroller with CAN.

ADC programming to read the motor speed using IR Sensor and read temperature using LM35
Sensor.

Depends upon measured temperature Master send controls message to Slave and motor speed
controlled.
Project#2
THE PARAMETRIC VOLTAGE MEASUREMENT SYSTEM
Tool
: AVR Studio, AT mega 8
Language
: Embedded C
Team Size
:2
Client
: IOCL
Description
This project consists of RISC based Microcontroller for monitoring the voltage and reporting it to
the end user. The microcontroller measures the voltage and stores it in the internal memory. The
microcontroller then fetches the data from the memory and sends it to the user through wireless
technology. The unit also consists of noise filtering system which increases the reliability of the unit.
Contribution:

UART Programming to interface At mega 8L with GSM module

Mobile numbers are stored in internal EPROM. Voltage read through ADC channel is
transmitted to the GSM module through UART and then sent out to the stored mobile
numbers through SMS.

GSM data can be received from mobile phones and are used to change the controller
default settings.

Information sent to the GSM server is voltage, time and date, percentage of battery
charge.
CERTIFICATIONS

PG Diploma in Embedded system and Design.

windows Networking

Project:
FPGA BASED DESIGN OF CDMA MATCHED FILTER FOR MULTI USER
DETECTION.
Organization : Anna University Tirunelveli.
Techniques
: DSSS\DS-CDMA, MMSE Detector, Matched Filter.
Tool
: Xilinx ISE8.1i
Language
: VHDL
Description
CDMA is a technique used for wireless data transmission. Every mobile handset and every
wireless base station operate on the same frequency spectrum. In order to discriminate one conversation
from another, every handset broadcasts a unique code sequence. CDMA base stations must be able to
discriminate these different code sequences in order to distinguish one transmission from another. This
discrimination is accomplished by means of a matched filter, whose output indicates when a particular
code sequence is detected in the input data stream. This application note includes a reference design
(HDL code) for implementing parallel matched filters.
