5. Operational Amplifiers Introduction In many electronic circuits‚ the signals (voltage differences) that are generated and manipulated are very small. Therefore‚ amplification is often essential. When playing a CD for instance‚ the signals generated in the CD player are quite small and will not adequately drive a speaker system. The signals from the CD player are therefore passed into the stereo amplifier (which often comes as a tuner/amplifier combination in modern home stereo systems)

present in the breath is oxidized into acetic acid while passing over the heating element. This ethyl alcohol falls on the tin dioxide sensing layer and as a result its resistance decreases. This resistance variation is converted into a suitable voltage variation using an external load resistor. The typical connection arrangement of an MQ135 alcohol sensor is shown below. 6/9/2013 12:44 AM Alcohol breathalyzer circuit using 8051 microcontroller.

LDR will be very less. Here 555 timer IC is configured as a monostable multivibrator. The LDR will trigger the 555 timer. The output of the 555 timer IC is directly fed to the baser of the transistor. This gives low signal and it turns ON the coil voltage of the relay. Street lights were connected to relay.

1 IDENTIFICATION OF BASIC ELECTRONIC COMPONETS THEIR CHARACTERISTICS & TESTING 1.0.0 INTRODUCTION An electronic circuit is composed of various types of components. Some of these components are termed as active components because they take part in the transformation of the energy while other components‚ which only dissipate or store energy‚ are called as passive elements. The vacuum tubes‚ rectifier‚ transistors are some of-the common active while the resistances‚ which dissipate the power
