On the PLC in the automatic door control system
In supermarkets, public buildings, banks, hospitals and other imported, often using the automatic door control system. The early automatic door control system uses relay logic control, has gradually been phased out. PLC controlled automatic doors as a low failure rate, can be * high, convenient maintenance, which is widely used.

two basic requirements for automatic door control

1 was close, the door should automatically open.

2 door opened, the state should be kept open until the d ....etc

automatic door opening system using pir sensor

The system puts forward an automatic and precise door opening system based on human movement sensing near the door. Well opening a door in places like hotels, Shopping complexes, and offices can be a tedious task and sometimes requires hiring a person just for the sake of opening door whenever a person arrives.Well this project proposes a system that allows for automatic door opening solution by sensing human presence near it. Our system achieves this functionality with the help of PIR sensors. PI ....etc

A system of automatic opening and closing of the door by detecting any movement of the body near the door. This is achieved with the aid of a PIR (infrared passive) sensor. A living body generally emits infrared energy which is detected by the PIR sensor from a considerable distance. This detection signal is fed to a micro-controller to operate a gate motor through the IC motor controller.When a body approaches within the operating range of the sensor, it sends a logic command to open the door. The door closes automatically with a fixed time de ....etc
