Movement Sensed Automatic Door Opening System Introduction: Opening and closing of doors is always a tedious job, especially in places like shopping malls, hotels and theatres where a person is always required to open the door for visitors. Automatic opening and closing of door by sensing any body movement near the door is achieved with the help of a PIR (Passive Infrared) sensor. A motion detector is a device that detects moving objects, particularly people. A motion detector is often integrated as a component of a system that automatically performs.

Movement Sensed Automatic Door Opening System Passive Infrared Sensor (PIR): PIR sensors detect a person’s body heat when the person comes in close proximity. These sensors are small, low power, inexpensive and easy to use. Due to these reasons, PIR sensors are generally used in gadgets, home appliances, business enterprises, industries, etc. PIR gives digital output when it detects motion. It consists of pyro-electric sensor that detects the infrared radiation emitted from humans.

Movement Sensed Automatic Door Opening System How do automatic doors work? A live body generally emits infrared energy which is sensed by the PIR sensor from a considerable distance. This sensing signal is fed to a microcontroller to operate a door motor through motor driver IC. When a body approaches within the operating range of the sensor, it sends a logical command to open the door. The door automatically closes with a fixed time delay. If there is no further movement within the PIR operating range. Interrupt signals are used through switches to avoid locked rotor of motor. http://www.edgefxkits.com/

Movement Sensed Automatic Door Opening System Advantages of automatic door: ďƒ˜ For people in wheelchairs and other disabled individuals, automatic doors are an immense boon, since conventional doors can be very hard to work with. It may be impossible to open a conventional door while seated in a wheelchair or navigating with crutches. ďƒ˜ In hospitals and scientific labs, automatic doors can be used to secure an area by ensuring that the doors are shut at all times, while reducing the risk of cross-contamination since people do not need to handle the doors to pass through them. ďƒ˜ Automatic doors can also be useful in warehouses and other facilities where people frequently have their hands full, contributing to safety and efficiency by making it easier for people to get around. http://www.edgefxkits.com/
Movement Sensed Automatic Door Opening System Further Improvements: ďƒ˜ For an improved, effective system to be implemented and achieved, the following suggestions should be considered for further work. ďƒ˜ There can be a Display Unit for showing number of persons entered in a particular room. ďƒ˜ A better sensor is recommended to achieve new functionality. For instance, a suitable sensor such as radar sensor that could detect contraband goods in any vehicle.

Movement Sensed Automatic Door Opening System To achieve full automation, a real time system should be employed and a Closed Circuit Television (CCTV) system provided for proper monitoring and security purposes. This can be helpful in detecting the presence of vehicles before the system is activated. Upgrading the system using higher bit microprocessors for speed optimization. Along with this system we can use Face-detection through Camera for Automated Attendance System.

Movement Sensed Automatic Door Opening System Conclusion: Further this can be enhanced interfacing a counting arrangement for keeping a record of entry and exit of people at particular place. This can be achieved by interfacing the system with an EEPROM (nonvolatile memory) to avoid loss of stored data even if the power fails. Movement Sensed Automatic Door Opening System is very useful.
