Digital voltmeter using 89c51 microcontrollerSaylee joshi
Voltmeter is a voltage measuring instrument.
We can measure the potential difference between any two points in an electrical network using voltmeter.
There are two types of voltmeter as analog voltmeter and digital voltmeter.
Analog voltmeter moves pointer on a scale but it has some limitations like accuracy of few percent of full scale.
Digital voltmeter can display numerical value of voltage on a display by use of analog to digital converter (ADC).
All the data processing and manipulating is in digital form, so it is very essential to use ADC.
We have used ADC0804 analog-to-digital converter IC. The range of input voltage is 0-15V. Here the input voltage should be DC voltage so as to get the steady output on the LCD display.
If you give the AC voltage as an input, it will display continuously running numbers as the nature of AC voltage.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2. INTRODUCTION
• As the computer technology advances, the
performance and the availability of the PCs and Laptop
become reliable, common and also the prices are
falling drastically. Thus, the design and development of
the low cost PC based DAS using microcontrollers for
use in various fields has been a challenging task.
• Physical parameters such as temperature, pressure,
humidity, light intensity etc., are generally slowly
varying signals. They can be sensed by respective
sensor or transducer giving changes in electrical
parameters.
4. MATERIALS USED
• AT80C51 Microcontroller
• Temperature Sensor(LM 35)
• Humidity Sensor(HIH 4000 series)
• PIC18F4550
• USB connector
• Capacitor(470nF,22pF)
• Resistance(470,100K,47K,10K,330K,1M)
• OP AMP(OP07)
• Diode
• Crystal Oscillator(12MHz)
5. THEORY
• DAQ (Data Acquisition) is defined as the process of
taking a real-world signal as input, such as a voltage or
current any electrical input, into the computer, for
processing, analysis, storage or other data
manipulation or conditioning.
• A Physical phenomenon represents the real-world
signal we are trying to measure. Today, most scientists
and engineers are using personal computers with ISA,
EISA, PCI or PCMCIA bus for data acquisition in
laboratory, research, test and measurement, and
industrial automation applications.
8. SIGNAL CONDITIONING
Electrical signals are conditioned so they can be used by an analog input board. The
following features may be available:
• Amplification
• Isolation
• Filtering
• Linearization
Amplifier: The output voltage from the sensor would be fed to the amplifying
circuit input .The output of the sensor is in milli volt so we need to amplify it to fetch it
to the input range of PCL card 208.
10. USE OF ADC
Signal processing applications deals with converting analog signals into digital values and
vice versa The goal of an A/D transformer is to make a decision on the output digital word
matching to an analog input signal. The A/D transformer operates on the successive
approximation principle. Analog switches are closed consecutively by successive-
approximation logic until the40 analog differential input voltage [Vin(+) - Vin(-)] matches a
voltage derived from a tapped resistor string across the reference voltage. The normal
process proceeds as follows. On the high to-low transform of the WR input, the internal SAR
latches and the shift-register stages are reset, and the INTR output will be set high. Only if the
CS input and WR input stay low, the A/D will remain in a reset state. Conversion start from 1
to 8 clock periods after one of these inputs makes a low-to-high transition. After the
necessary counts of clock pulses to complete the conversion, the INTR pin will make a high-
to-low transition. This can be used to interrupt a processor, or or else signal the availability of
a new conversion.
13. AT80C51
The logical separation of program and data memory allows the data memory to be accessed
by 8-bit addresses, which can be rapidly stored and manipulated by an 8-bit CPU.
Program memory (ROM, EPROM) can only be read, not written to. There can be up to 64k bytes
of program memory. In the 80C51, the lowest 4k bytes of program are on-chip. In the ROM less
version, all program memory is external. The read strobe for external program memory is the
PSEN (program store enable).Data Memory (RAM) occupies a separate address space from
Program Memory. In the 80C51, the lowly 128 bytes of data memory are on-chip. Up to 64k
bytes of external RAM can be addressed in the external Data Memory space. In the ROM less
version, the lowest 128 bytes are on-chip. The CPU generates read and write signals, RD and
WR, as needed for the period of outside Data Memory accesses. External Program Memory and
external Data Memory may be combined if desired by applying the RD and PSEN signals to the
inputs of an AND gate and using the output of the gate as the read strobe to the external
Program/Data memory.
14. Advantages & applications
• Low Cost
• Flexible
• Low Power Consumption
Applications-
• Can be used in industries
• Can be used in nuclear plants
• Can be used in mines
15. CONCLUSION
Here in our project we have designed a data acquisition system using AT80c51
microcontroller and ADC0804LCN analog to digital transformer. The designed
model was programmed in assembly level language for single analog input and
was tested under proper condition. Also we have used PCL-208 as an interface to
realize PC based data acquisition in partial fulfillment. Owing to shifting of most
instrumentation system towards PC compatibility it offer more advantage
compared to 89c51 based data acquisition system. Also it is more flexible as
program can be changed according to requirement repeatedly.
