Automatic Accident Avoidance System (using Alcohol Level Sensor) for Automobiles

Driving under the influence of alcohol is a problem that has affected countless lives and properties, like when this drunken driver (the man on black shirt) hits my wife's red car and later ran away. I was motivated to design a system that can assist the police or road safety officers to check over speeding drivers

When a vehicle driver is drunk, the driver will be at higher risk to terminate the lives of the passengers, pedestrians and other people that may be at the roads.  There is a serious need to incorporate this project in every vehicles to automatically disable the vehicle engine if the driver is drunk. Another incident of a reckless driving as a result of  high influence of alcohol personally affected me and the drunken driver hits my white car below:   

Thank God for saving my life and the lives of my family in the vehicle that day. Therefore, for the purpose of safety, this work involves the design and implementation of a circuit that can be used as an automatic accident avoidance system (using alcohol level sensor) for automobiles. It can be installed as an in-built vehicle accident prevention system, recommended for all vehicle which uses alcohol sensor with programmed micro-controller to prevent the vehicle engine or ignition from functioning once high rate of alcohol is detected in the vehicle towards the drivers sit. The project can assist companies and traffic police officers to determine whether someone is drunk and is fit to drive or not. It plays an important role in an effort to reduce traffic accident cases based on driving under the influence of alcohol. The alcohol sensor used in this project is MQ-3 which is very effective in detecting the presence of alcohol in human breath.

 The alcohol sensor is also sensitive to ammonia, carbon dioxide, alcohol, smoke, nitrogen dioxide, etc.  It consists of a tin dioxide sensitive layer inside aluminum oxide micro tubes, measuring electrode and a heating element inside a tubular aluminum casing. The front end of the sensor is covered using a stainless steel net and the rear side holds the connection terminals.

T JUCTION TRAFFIC LIGHT SYSTEM

Traffic congestion is a severe problem in many modern cities around the world. It has been causing many critical problems and challenges in the major and most populated cities. To travel to different places within the city is becoming more difficult for the travelers in traffic. Due to these congestion problems, people lose time, miss opportunities, and get frustrated. Traffic congestion directly impacts the companies. Due to traffic congestion there is a loss in productivity from workers, trade opportunities are lost, delivery gets delayed, and thereby the costs goes on increasing. 

The project T junction traffic light system was designed to tackle the traffic congestion issues in the country, so as to establish automatic traffic control. The project was designed using AT89C51 micro-controller which is the brain that initiates the traffic signal at the junctions. The LED’s are automatically on and off by making the corresponding port pin of the micro-controller high.  At a particular instant only one green light holds and other lights hold at red. During transition from green to red, presents the yellow LED and succeeding group yellow LED glows and then succeeding group LED changes to green. This process continues as a cycle. 

 In this design we have implored the use of both hardware and software to bring about the entire project. The hardware components are solely coordinated by the AT89S51 micro-controller chip while the ASM programming language is used to program the chip

48v to 30v power supply using 15v zener diode

This is a 48v to 30v power supply I designed for a friend today. He is one of the good friends i got from using internet. He wants to create 30v power supply using a 15v zener diode so this circuit was designed and simulated in ISIS Professional Protues 8.3 for him.

Please feel free to test and use it.  You can always make a comment to this post to share your experience on the circuit or tell us where we can help you more.

The next version of the circuit will use micro-controller to display the output voltage and automatically shuts down the system when the input voltage is low.

Digital Clock with Calendar

This project is a digital clock with calendar which you can build at home with few components. it can be used as a final year school project for those that studied electronics, electrical and computer engineering. The power supply unit which has a 7805 voltage regulator supplies the required regulated voltage to the appropriate connections of the overall circuit. 

The microcontroller controls the general operation of the circuit; all the other units are interfaced to it. The input unit is activated by pressing the keypad (buttons) unit to call up the subroutine program that controls the set date, month, year and time instructions. The  microcontroller executes the instruction codes which displays the time and date on an LCD.
