PIC Micro controller Data Acquisition System Project Report

Introduction:

The debugging of an electrical circuit can be done by knowing the voltage , temperature and current information. By providing the data acquisition system in the power supply  we can know these values . this paper concentrates on developing a data acquition system which measures the voltage from 0 to 50v, current values up to 50 amps and finds temperature on the ambient and load.

Construction of data acquition system:

The current voltage and temperature sensors are used which gives the sensed information during the working of the circuit the sensed information from the sensors is fed to analog to digital converter, which is a 14 pin package. For monitoring the process a pic micro controller is used. From the available pic microcontroller’s we need to select the required one which has a 4adc channels and counter timer and quart. For the pic microcontroller to operate accordingly we have to provide it with the data. The internal oscillator frequency is set to 4mhz for its working. The baud rate at which the data is transmitted is 9 bits in which one bit  is used for stat or stop information and the other 8 bits are used for data information. To control the sampling rate timer is used and by polling the overflow bit are controlled. The micro chip on the pic microcontroller provides environment for compiling coding setting up and controlling programs. The flash memory of the pic can be reprogrammed by using the interface ide of usb. By using RS232 and max232 the transfer of digital data is possible in between the pc and thru registers of the microcontroller.

 Conclusions’ and Future scope:

Here the complexity of the project increases due to selection of the pic microcontroller other than a normal microcontroller. The data acquisition system can be further developed by the use of high resolution ADC converters. Here the chances of crashing occurs when the captured data is plotted on a excel sheet, which can be overcome by use of high integrated capture display programs.

Smart Window Electronics Project Report

Introduction to Smart Window Electronics Project:

The most nagging part of a summer is of course the unbearable heat generated from the sun rays gazing through our home & office windows, on contrary during winter season we wish it would be warm inside. There was a need of a glass which behaves and adjusts its characteristics depending on external weather factors. Sunrays consist of which brings harm for the human body, it is essential to cut off them before it reaches us. Smart windows are a creative and futuristic solution to all the above problems; it can be controlled like a fan is controlled by its regulator. Composite glasses are used to adjust the heat characteristics of the sunlight and also to prevent the harmful radiations from penetrating through it. All smart windows are air, water tight and are also resistant to high speed winds.  

Advantages of Smart window Electronics Project:

  • Can control the heat in the room by changing the texture of the glass electrically
  • Harmful radiations such as UV rays, Gamma rays are blocked effectively
  • Makes place warmer during winter, cooler in summer
  • Energy conservation and no need of curtain or shade fittings
  • Huge potential business in the future

SMART WINDOW TYPES:

Electro chronic window has various levels of materials such as glass panels, conducting oxides, EC Layer, Ion conductor and storage etc.  When electricity is passed through it, ions will be transferred and as a result a layer of oxide will be the positive electrode and tungsten oxide will be the negative electrode which will eventually result in darkening of the glass. In liquid crystal windows, a layer of liquid crystal are sandwiched between two films which on power supply will make the glass clear from a glazing state? Thermo chromic windows cut off heat using gel based coating changing the window state from transparent to light opaque and reflective.  Photochromic technology changes the glass color but rarely reduces the heat. Suspended particle devices (SPD) is the latest among other technologies, it contains two panels of glass, a conductive material, millions of suspended black particles, liquid suspensions and a control device. This technology can provide far more efficient cutting of heat than other technologies and also can switch the process swiftly

Multi User CDMA Communication System Project Report and Mat Lab Code

Introduction to Multi User CDMA Communication System Project:

Multi user CDMA communication system project is for B.S.C communication engineering students. Main aim of this project is to implement a simple experimental setup for understanding wireless communication using sound waves instead of electromagnetic waves. These experimental results will be further designed at lab environment by using transmitter and receiver using electromagnetic waves. Initially entire application is tested using speaker and microphone. 

Problem Specification: 

Using CDMA technology we need to design a real time acoustic communication system. This application should effectively work in laboratory environment. With this simple design we must transmit information from transmitter to receiver acoustic channel. This application should transmit information on eight different channels at same time. 

Along with project design this project report covers details on different wireless communication and modulation techniques and cover information on topics like study on multiple access techniques, transmitters, receivers, channels, synchronization, modulation and de modulation techniques. 

Some of observations that can be made during this project are we can use Walsh code in place of other codes because this system works for short distance and because of this reason there is very less multipath present. BPSK is the modulation technique is used in this project because of limited data rate provided by sound card. 

Here we provide full project documentation with mat lab code for 4 channels and 8 channels.
