Introduction: An oxygen sensor‚ or lambda sensor‚ is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed. It was developed by Robert Bosch GmbH during the late 1960s under supervision by Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ceramic coated on both the exhaust and reference sides with a thin layer of platinum and comes in both heated and unheated forms. The most common application is to measure the

EXPERIMENT NO. 10 Thevenin’s Theorem Objectives: 1. To verify the Thevenin’s theorem through an experiment. 2. To find the Thevenin’s resistance RTH by various methods and compare values. Equipment: Resistors‚ DMM‚ breadboard‚ DC power supply‚ and connecting wires. Theory: Thevenin theorem states that any linear two-terminal circuit can be replaced by an equivalent circuit consisting of a voltage source VTH in series with a resistance RTH where * VTH is the open-circuit voltage at

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

electricians follow the National Electrical Code‚ and State and local building codes. A day-in-the-life can consist of connecting all types of wires and circuit breakers‚ outlets‚ and a host of other components. Their use of tools include: ammeters‚ ohmmeters‚ voltmeters‚ oscilloscopes‚ and other equipment used in electrical testing. Their work includes making regular assessments of electrical equipment and electrical systems. Most of their work involves adding and replacing wires‚ fuses‚ circuit breakers

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
