Automatic Door Sensor How It Works

The earliest electronic home security system was entirely made up of door sensors when someone opened a door or window it triggered a big vibrating bell in a central part of the home. This releases the reed switch and the sensor alerts the panel. A door contact sensor works using a sensor and a magnet.

Automatic door sensor how it works.

Door sensor working of a door sensor. Proximity sensors only need to pick up on changes in the beam to activate the door. These sensors are usually mounted above the door and they emit an electromagnetic or infrared beam and look for changes in the projected field. Motion detectors or optical sensors.

Widely used in different co. These days most automatic doors use motion detection sensors or optical sensors which are installed on the sides of the door to trigger the opening closing of. Several types of automatic doors are outfitted with proximity sensors. That s why door sensors also known as entry sensors window sensors or contact sensors are some of the most popular home security devices.

There are different types of door sensors available in the market. We have placed ourselves as the leading manufacturer exporter and supplier of a world class collection of automatic sensor door. Most of these sensors use a reed switch a magnet to decide the status of a door whether it is opened or closed. When the door is opened the magnet is separated from the sensor.

The sensor has an internal reed switch that is closed when it is in direct proximity with a magnet. This pressure sensor would detect the presence of people in the area based on weight and facilitate the automatic opening and closing of the door.
