value into a suitable number in Celsius scale which is done by the ADC0804. The temperature sensed in Celsius scale is converted into the Fahrenheit scale temperature just by using the Celsius to Fahrenheit conversion formulae. This project also uses 8051 microcontroller (AT89C51). Keywords— Celsius‚ Fahrenheit‚ ADC 2. INTRODUCTION A digital thermometer can be easily made by interfacing a temperature sensor to the microcontroller AT89C51. The temperature sensor

ABSTRACT According to Election Data Services the percentage of electronic voting machines per county doubled between 1998 and 2002 to 16 percent-‚ yet a full replacement of the traditional voting procedure is very unlikely. In its essence‚ an electronic voting machine is a computer assisted self-interviewing device (CASI) giving the voter the opportunity to review and change his/her vote before submitting it. The different types of voting machines allow for different kinds of interaction

RFID BASED ATTENDANCE CUM SECURITY SYSTEM [pic] Submitted By: INTRODUCTION Our final year project is RFID based Attendance cum Security System. This idea came to my mind when I saw our lecturers taking the attendance of 100s of students very hardly. We thought we can integrate the RFID based Security System with attendance system as well. That what our final year project is doing. BLOCK DIAGRAM OF THE PROJECT: [pic] History of RFID: In a very interesting article
