PowerPoint Presentation on Data Logger System

Training At Bhabha Atomic Research Centre

Download

Data Logger System Presentation Transcript:
1. A premier multi-disciplinary Nuclear Research Centre of India having excellent infrastructure for advanced Research & Development with expertise covering the entire spectrum of Nuclear Science & Engineering & related areas.

2. FOUNDER
Homi Jehangir Bhabha was the visionary who conceptualised the Indian Nuclear Programme and along with a handful of Scientists initiated the nuclear science research in India in March, 1944. His own words “When Nuclear Energy has been successfully applied for power production in, say a couple of decades from now, India will not have to look abroad for its experts but will find them ready at hand”.

3. The Atomic Energy
Establishment, Trombay (AEET) was formally dedicated to the nation by the then Prime Minister Pt. Jawaharlal Nehru on January 20, 1957. Later, Prime Minister Indira Gandhi renamed AEET as Bhabha Atomic Research Center (BARC) on January 12, 1967 as a fitting tribute to Dr. Homi Bhabha who died in an air crash on January 24, 1966.

4. DATA LOGGER
Data Logger: A device that can read various types of electrical signals and store the data in internal memory for later download to a computer.

5. APPLICATIONS
Unattended weather stations recording. Unattended hydrographic recording. Unattended soil moisture level recording. Unattended gas pressure recording. Wildlife research.

6. MICRO-CONTROLLERS
A microcontroller is a small computer on a single integrated circuit consisting of a relatively simple CPU combined with support functions such as a crystal oscillator, timers, watchdog, serial and analog I/O etc. 89C52 is a 40 pin ┬Ác IC. T2CON, SCON, IE control words.

7. MAX 197 IC
ADC and 8x1 MUX. Uses successive approximation technique. 8 analog i/p channels. Data bus bidirectional. 12-bit data, (8+4).

8. PIN DESCRIPTION
28 pin IC. CH0-CH7 channel pins. HBEN pin. Clk, RD, WR, CS pins. SHDN pin. INT pin.

9. SUCCESSIVE APPROXIMATION
ADC uses successive approximation and internal input track/hold (T/H) circuitry to convert an analog signal to a digital output.
