Our mission of this project is to identify the presence of alcohol from driver side and inform owner (in the case of rented vehicle) / police control room / KSRTC control room (In the case of KSRTC buses) about this. Thus owner / Police can access the ignition control of the vehicle from a remote place and can switch on/off the vehicle through mobile phone. It reduces the chance of occurring accidents due to the drunken driver. The system also informs if any accident occurs on the vehicle. The main parts of this project are microcontroller (8051), GSM, Alcohol sensor and vibration / shock sensor. Microcontroller is the heart of this project. Alcohol and shock sensor outputs are given to the microcontroller. Microcontroller monitors these inputs continuously. If any abnormal condition (like the presence of Alcohol more than a preset level) occurs inside the vehicle, the system informs the police / owner about this by sending SMS automatically. The message is send using GSM modem through GSM network. The controller communicates with the GSM modem via AT commands through MAX 232 interface. Thus owner / Police can access the ignition control of the vehicle from a remote place and can switch on/off the vehicle through mobile phone by sending an SMS. This is accompanied with an alarm. And if any accident occurs, it is detected by the shock sensor and automatically send accident message to the police / owner. 2014-02-02T00:00:00Z http://hdl.handle.net/123456789/2554 SPEED CONTROL OF DC MOTOR USING MICROCONTROLLER LOISY P.L; MANU G; MEENU GIBI The aim of developing this project is to control the speed of DC motor. The main advantage in using a DC motor is that the Speed-Torque relationship can be varied to almostany useful form. To achieve the speed control an electronic technique called Pulse WidthModulation is used which generates High and Low pulses. These pulses vary the speed in themotor. For the generation of these pulses a microcontroller (ATmega16A) is used.Since DC motor has wide range of applications, controlling its speed has a good relevance 2014-02-02T00:00:00Z http://hdl.handle.net/123456789/2551 SMS CONTROLLED DEVICE BIBI BANERJI; BASIL GEORGE; ATHUL S CHANDRAN SMS Controlled Device is incorporated using PIC 16F876A micro controller and a relay. Relay is an electromechanically actuated switch and is triggered by the input of the micro controller. The relay status are shown in the LCD and is configured by programming the PIC 16F876A microcontroller. The components are soldered and done in PCB(Printed Circuit Board). PCB is designed with Cadsoft Eagle Proffessional software. The program is done in MickroC_Pro_Pic. The program is stimulated and checked with Proteus Proffessional V8 software. Program burner used is ICD2. 2014-06-02T00:00:00Z http://hdl.handle.net/123456789/2545 RFID CONTROLLED MULTIPLE USE ALARM SYSTEM PRIYA P; RESMA OMANAKUTTAN; SHILBY BABY In this new era of automation everything is done by either man controlled or some parameter controlled equipments. Mission of our project is to check the absence of any person after an allotted time using microcontroller and RFID module. The presence of each person is determined using the RFID tag provided to each member. If any member is found missing after allotter time, the buzzer will become on and can be made off only if that missing person come. The provision to off the alarm for the authorized personnel using his tag is also provided. The main parts of this project are microcontroller (PIC16F877A), RFID tag and reader. Microcontroller is the heart of this project. RFID reader outputs are given to the microcontroller through serial communication ports. Microcontroller monitors these inputs continuously. If any missing is found after the allotted time, the microcontroller will send the signal to LCD display and buzzer. So the authorized person is informed about the missing and he can off the alarm using his RFID tag. MAX 232 interface is used in serial communication between RFID module and the microcontroller. 2014-01-02T00:00:00Z
