Introduction to Pulse Width Modulation (PWM)
In this technique several pulses are produced in each half – cycle but the width of the pulses
is not the same as in case of multiple – pulse width modulation, however the width of each pulse is
varied in accordance with the amplitude of the sine wave reference voltage. The width of the pulse
at the center of the half – cycle is maximum and decreases on either side. The figure 6(a) shows the
generation of the output signal by comparing a sinusoidal reference sign ....etc

hi sir/madam ,

Our project is based on agricultural we r using a two energy sources for running a motor.two energy sources means kptcl n solar power.here we r using gsm because the farmer need to send a message to microcontroller like start the motor so microcontroller can automatically on the motor through the relay circuit.and when the soil can wet at its reaching threshold value the motor can automatically turn off and sends a message to farmer like motor off. and also whenever the motor having problem the microcontroller sends mess ....etc

ABSTRACT:
Due to the drastic changes in technology in the last decade, so many advancements were introduced in electricity departments. The electricity bill can be paid now through E-Seva centers, ATMs, Net-banking and even through mobile phones. But prepaid electricity is a unique and new concept which saves lot of time and a power for electricity department. In this system the user has to purchase an EEPROM based recharge card and it should be inserted in the slot provided on prepaid energy meter ki ....etc
