ADVANCE CAR JACK CONTROLLED BY RF WIRELESS DEVICE
The project is designed to control the direction of car jack by using a RF technology for remote operation with a transmitter and receiver. The direction of the DC motor is depending on signal which is coming from transmitter. Hence, if the relay 1 & relay 4 gets ON then the motor rotates in forward direction. And if relay 2 & relay 3 gets ON then the motor rotates in backward direction.
ANDROID CONTROLLED CAR JACK
The project is designed to control the direction of car jack by using an android phone with the help of Bluetooth device. The direction of the DC motor is depending on the signal which is coming from mobile. Hence, if we press UP, this is present on your mobile then the relay 1 & relay 4 gets ON, so the motor rotates in forward direction. And if when we press DOWN from mobile the relay 2 & relay 3 gets ON then the motor rotates in backward direction.
AUTO INTENSITY CONTROL OF STREET LIGHTS
Red Light Emitting Diodes (LED) replaces HID lamps in street lighting system to include dimming feature. A microcontroller of 8051 family is used to control the intensity by developing pulse width modulated signals that drives a MOSFET to switch the LEDs according to achieve desired operation.
AUTOMATIC POWER FACTOR CORRECTION USING PIC- MICROCONTROLLER
In this proposed system, two zero crossing detectors are used for detecting zero crossing of voltage and current. The project is designed to minimize penalty for industrial units using automatic power factor correction unit. The PIC microcontroller used in this project .
The time lag between the zero-voltage pulse and zero-current pulse is duly generated by suitable operational amplifier circuits in comparator mode is fed to two interrupt pins of a microcontroller. The program takes over to actuate appropriate number of relays from its output to bring shunt capacitors into load circuit to get the power factor till it reaches near unity.
Automatic Train Traffic Gate Control
Automatic Railway Gate Control System is a simple but very useful project, which help is automatically opening and closing the railway gate upon detecting arrival or departure of the train.In general, Railway gates are opened or closed manually by a gate keeper. The information about arrival of train for opening or closing of door is received from nearby station. But some railway crossings are totally unmanned and many railway accidents occur at these unmanned level crossings.
