SPEED CHECKER TO DETECT RASH DRIVING ON HIGHWAYS
$90.15$60.10The aim of this project is to develop a device to detect rash driving on highways and to alert the traffic authorities in case of any speed violation. Accidents due to rash driving on highways are on the rise and people are losing their lives because of others mistakes. In the present system, to detect rash driving the police has to use a handheld radar gun and aim at the vehicle to record its speed. If the speed of the vehicle exceeds the speed limit, nearest police station is informed to stop the speeding vehicle. This is an ineffective process as after detecting one has to inform the same and a lot of time is wasted.

SPEED CONTROL OF INDUCTION MOTOR USING ACPWM
$100.97$88.95This project attempts a new speed control technique for the single-phase a.c. induction motor. It presents a design of a low-cost; high-efficiency drive capable of supplying a single-phase a.c. induction motor with a PWM modulated sinusoidal voltage. The circuit operation is controlled by an 8051 family microcontroller.

Speed Control Of Induction Motor Using Firing Angle Control
$90.15$70.92The main object of this project is to develop speed control of two induction motor using firing angle control system which is helpful to control the speed of an induction motor using microcontroller
In this project, the zero-crossing point of the voltage waveform is detected by a comparator whose output is then fed to the microcontroller. Then, it provides the required delayed triggering pulses to a pair of TRIAC through an opto-isolator connected to this circuit. Finally, power is applied to the load through the TRIAC. Four push-button switches are interfaced to the controller for increasing and decreasing the AC power to the load. In this project, a lamp is used in the place of induction motor demonstration purposes. The motor speed variation depends on the power reduction.

SPEED CONTROL OF TWO INDUCTION MOTOR USING ACPWM
$126.21$103.37This project attempts a new speed control technique for the single-phase a.c. induction motor. It presents a design of a low-cost; high-efficiency drive capable of supplying a single-phase a.c. induction motor with a PWM modulated sinusoidal voltage. The circuit operation is controlled by an 8051 family microcontroller. The device is aimed at substituting the commonly used triac phase angle control drives. The circuit is capable of supplying a single-phase a.c. induction motor (or general a.c. inductive/resistive load) with varying a.c. voltage. The same as in triac control, the voltage applied to the load can be varied from zero to maximum value. On the other hand, it uses a pulse width modulation technique (PWM), and when compared with the phase angle control used for triacs, produces much lower high order harmonics.

STREET LIGHT THAT GLOWS ON DETECTING VEHICLE MOVEMENT
$90.15$60.10This project is designed to detect a vehicle movement on road to switch on only a block of street lights that are ahead of the vehicle, and to switch off the glowing lights when the vehicle passes away from the lights. This will help to save electrical energy.

SUN TRACKING SOLAR PANEL
$90.15$60.10This project employs a solar panel mounted to a time-programmed stepper motor to track the sun so that maximum sun light is made incident upon the panel at any given time of the day. This is better compared to the light-sensing method that may not be accurate always – for example, during cloudy days.

Sun Tracking Solar Panel
$156.26$144.24In this project, LDR’s are working as light detectors. Before we go into detail, we will have to understand how the LDR’s work. LDR (Light Dependent Resistor) also known as photo resistor is the light sensitive device. Its resistance decrease when the light falls on it and that’s why it is frequently used in Dark or Light Detector Circuit. Check the various circuits based on LDR here.

SUN TRACKING SOLAR PANEL TO TRACK THE MAXIMUM RAYS BY USING SERVO MOTOR
$114.19$88.95This project employs sun tracking solar panel to track the maximum rays by using servo motor. This is better compared to the light-sensing method that may not be accurate always – for example, during cloudy days. With the impending scarcity of non-renewable resources, people are considering to use alternate sources of energy. Barring all the other available resources, the solar energy is the most abundant and it is comparatively easy to convert into electrical energy. The usage of solar panel to convert Sun energy into electrical energy is very popular, but due to the transition of sun from east to west, the fixed solar panel may not be able to generate optimum energy. The proposed system solves this problem by an arrangement for the solar panel to track the maximum Sun rays.
