    Sun is an abundant source of energy and this solar energy can be harnessed successfully using solar photovoltaic cells and photovoltaic e ect to convert solar energy into electri- cal energy. But the conversion e ciency of a normal PV cell is low. One of the main reason for this is that the output of PV cell is dependent directly on the light intensity and with the position of the sun in the sky changing continuously from time to time; the absorption e ciency of an immobile solar panel would be signi cantly less at certain time of the day and year; for the solar photovoltaic cells are maximum productive when they are perpendicular to the sun and less productive otherwise. So to maximize the energy generation and improve the e ciency; solar trackers come into play. This paper presents the design and construction of an inexpensive active solar tracking system for tracking the movement of the sun so as to get maximum power from the solar panels as they follow the sun. It uses Light Dependent Resistors to sense the position of the sun which is communicated to a Arduino Uno microcontroller which then commands a set of two servo- motors to re-orient the panel in order to stay perpendicular to the sun rays. The design was constructed successfully and tested using Lab View to determine the improve- ments in e ciency. Evaluation results show that the new system performs 13.4percent better than the immobile solar PV system. Solar energy with solar tracking, will become possible to generate more energy since the solar panel depend on sun.Light Dependent Resistor(LDRs) are used for sunlight detection. To solve the electricity problem we uses solar and battery to save power which provide the user the availability of electricity. Here we are focusing on less power consumption and more performance device.

    Domestic power saver
    (AIKTC, 2017-05) Shaikh, Meenaz; Ansari, Adil (14DET47); Mehsania, Vasim (13ET29); Momin, Tabish (13ET32); Ahmed, Shabaz (13ET44)
    The project is designed to minimize penalty for industrial units by using automatic power factor correction unit. Power factor is defined as the ratio of real power to apparent power. This definition is often mathematically represented as KW/KVA, where the numerator is the active (real) power and the denominator is the (active + reactive) or apparent power. Reactive power is the non working power generated by the magnetic and inductive loads, to generate magnetic flux. The increase in reactive power increases the apparent power, so the power factor also decreases. Having low power factor, the industry needs more energy to meet its demand, so the efficiency decreases. In this proposed system the time lag between the zero voltage pulse and zero current pulse duly generated by suitable operational amplifier circuits in comparator mode are fed to two interrupt pins of the microcontroller. It displays the time lag between the current and voltage on an LCD. The program takes over to actuate appropriate number of relays from its output to bring shunt capacitors into the load circuit to get the power factor till it reaches near unity. The microcontroller used in the project belongs to 8051 family. Further the project can be enhanced by using thyristor control switches instead of relay control to avoid contact pitting often encountered by switching of capacitors due to high in rush current.

    GPS and GSM based anti-theft vehicle system
    (AIKTC, 2018-05) Shaikh, Meenaz; Gaus, Pasha Abbas Ali (15DET57); Shah, Mohd. Aslam (15DET66); Momin, Kazim E (15DET68); Shaikh, Faizan (15DET74)
    Currently almost of the public having an own vehicle, theft is happening on parking and sometimes driving insecurity places. The safe of vehicles is extremely essential for public vehicles. Vehicle tracking and locking system installed in the vehicle, to track the place and locking engine motor. The place of the vehicle identi ed using Global Positioning sys- tem (GPS) and Global system mobile communication (GSM). These systems constantly watch a moving Vehicle and report the status on demand. When the theft identi ed, the responsible person send SMS to the microcontroller, then microcontroller issue the control signals to stop theengine motor. Authorized person need to send the password to controller to restart the vehicle and open the door. This is more secured, reliable and low cost.
