RFID based Car Parking System is a simple project that offers an efficient car parking management system with the help of RFID Technology. Car parking management in organizations and malls often consists of many tasks like issuing tokens, noting the check-in and checkout time, calculating fare and finally collecting the amount. As the number of vehicles is increasing, the problems faced by a manual parking management system are also increasing. Such problems can be eliminated to some extent by implementing an intelligent parking system where the entry and exit of cars are monitored and payment is made easy with sensor technology. This project deals with an interesting manner of security access based car parking system using an AT89C51 microcontroller and RFID Technology.
In daily life, there several types of accidents are occurring. Accidents may cause due to various reasons like brake failure, drunk, and drive, etc. Most of the accidents will occur due to over drunken drivers. In order to overcome this problem, this accident avoidance system project is implemented. This project uses an alcohol sensor which is used to sense the drunken person from 200ppm onwards. If the person is drunk, Firstly we check him whether he is dunked or not. Then, this module is placed in automobiles. If the driver is dunked then the sensor will detect the alcohol amount spent by the person and it will close by buzzing using a buzzer.
Thermal imaging device is a benefit to the armed forces like navy, army and air force because of its 24 hours working capability to perform well in all climate conditions. Thermal detectors capture the IR(Infrared) radiation produced by all objects above complete zero temperature. The temperature differences of the captured section are denoted as a hectogram. With the beginning of IR detector technology, the large cooled thermal detectors having moving parts and difficult cryogenic temperatures have changed into small, and less expensive uncooled microbolometers having no moving parts. Thermal imaging system due to its numerous advantages has various applications in the military and also defines.
It is widely used by the armed forces for border surveillance and law implementation. It is also used in ship accident avoidance and control systems. In the aviation industry, it seriously mitigates the dangers of flying in the night conditions. They are widely used in military flight to recognize, find and aim the enemy forces. Recently, they are also being merged in civil aviation for health checking of aircraft.
There are different types of projects based on the temperature indicator. Now, here we are explaining about the temperature indicator with the LED display by using a temperature sensor. This project shows the use of a V/F converter monitoring temperature in degree Fahrenheit (F). The benefits of the LED temperature indicator are it can calculate the room temperature, atmospheric temperature, and body temperature. This article discusses the block diagram & circuit diagram of the LED temperature indicator.
Now-a-days parents are getting too busy with their works and tend to forget about the child and babies. After a facing a small accident by the child and later parents notice it, will not affect much as they couldn’t able to stop the accident. To overcome from this small mishap to the kids called child monitoring system where, a PIR sensor is placed in the living of the child. Once the child starts to move in the living room from the placed where the child is placed then the sensor will alert the alarm. This sign will help the parents to monitor the baby and look after. This will prevent the child from many dangerous situations. In this article we will study about the PIR sensor circuit working and how it really monitors the child from all sorts of dangerous situations.
Touchscreens are electronic displays-cum-input devices used in a wide variety of devices today. Over the past few years, touchscreens went from a technological fantasy to something so widespread that it’s now considered standard. Go back a few decades, and touchscreens would be looked at as nothing short of magic. Yet here we are, using them in our daily lives. It’s quite wondrous to think that technology is advancing so rapidly that in a couple of years, even what we consider impossible now would be very much doable. If you’ve ever wondered about how this technology works, you’ve come to the right place!
Ever since the dawn of time, man has worked tirelessly to make life better. With the advent of computers and the internet, communication and information transfer has become extremely easy. But there’s always been one common way of interacting with these machines. [Read more…]
