The NaPiOn motion sensor is made by Panasonic electronics. The automatic door opener uses the Area Reflective Type.The Area Reflective Type emits infrared rays from an LED.The sensor sens out a ray of light towards the object/human body then uses the reflected light to measure the distance and determine whether there is a person within the given distance of the sensor. When a sensor detects a person within its circumference of sight, it sets an output non-contact switch to ON. This type of sensor uses a series of complex embedded motion sensors with manually operated Program activators which are push buttons and switches,safety sensors that ensures that the doors do not get in contact with the user, Entrance control system,wireless program switch and a remote control. Additional features such as fire alarm can be added
