Microcontroller Microchip 12F Series, 16F Series, 18F Series, 24F Series, 30F Series. MX32F Series. ?? Atmel 89C51. ??? ARM (Medium Density and High Density). PROJETCS IMPLEMENTED : NUCLEAR ENVIRONMENTAL MONITOR Role Firmware designer, Hardware Selector Microcontrollers and Language and Tools. PIC18F8722 and PIC 16F877A. Embedded C. Protocol implemented in this Project are SPI for Ethernet, I2C for RTC and External EEPROM, RS232 for GSM and Online Configuration. Overview This Instrument is basically used for Nuclear Power Plant. This Instrument is installed around the plant and if there is nuclear Exploitation, will be detected and will immediately be transmitted To the central console by GSM. Otherwise the central console will ask the data after every hour, and the instrument will reply the every minute and every hour average data with Time Stamp. AREA GAMMA MONITOR Role Firmware designer, Hardware Selector Microcontrollers and Language and Tools. PIC18F8722 . Embedded C. Protocol implemented in this Project are SPI for Ethernet, I2C for RTC and External EEPROM, RS232 for Online Configuration. Overview This instrument is used for measurement the strength of GAMMA Radiation Present on the Environment. And the resultant will be displayed at Graphical LCD Display. PORTAL MONITOR Role Firmware designer, Hardware Selector Microcontrollers and Language and Tools. PIC18F8722 . Embedded C. Protocol implemented in this Project are SPI for Ethernet, I2C for RTC and External EEPROM, RS232 Online Configuration. Overview This instrument is used as gate scanner. This will have six Detectors and three gates. A person will pass from these gates, and if founded any radioactive active material with them, the instrument will generate alarm signal. The beauty of the instrument is that it have self adjustment with surrounding. OTHER NUCLEAR PROJECTS Radiation Survey Meter(6 Versions), Sim Survey Meter(3 versions with RF Communication), Hand Foot Monitor, Body Scanner etc. PROJETCS IMPLEMENTED : Elevator SMART ELEVATOR Role Project Designer. Microcontrollers and Language and Tools. PIC18F4620, PIC 16F877A. Embedded C. Protocol implemented in this Project are I2C for RTC and External EEPROM, RS232 Online Configuration and GSM, CAN Bus for main Communication. Overview This Elevator Project is Two Wire based. All calls from all the floors will generate distinct code and will transmit to the system by CAN bus. If there is any problem with operation like mechanical switch block, any sub controller failure, this will generate SMS to the area technician and to the Central Maintenance System, with exact problem. REMOTE MENTAINANCE SYSTEM Role Project Designer. Microcontrollers and Language and Tools. PIC18F4620, PIC 16F877A. Embedded C. Protocol implemented in this Project are I2C for RTC and External EEPROM, RS232 Online Configuration and GSM, CAN Bus for main Communication. Overview This is used for Error Reporting system via GSM for the existing Elevator Product which was working on Parallel communication Protocol. This will scan all the inputs and outputs from the main microcontroller, and if anything is missing, than will generate SMS to the area technician and t the Central Maintenance System with Exact Problem. OTHER PROJECTS Car Security System(3 Versions), Home Automation Products(5 Versions), Serial Floor Indicator, Serial Call Generator, Serial Voice Announcing System, Multilink VDP Signal Generator(Telephone based) etc. Scored 91 percentile in GATE held in feb 2006 in Electronics and communication Engineering having the Gate score of 371 PERSONEL DETAILS.
