How does Dalang automatic door sensor work

We are all familiar with automatic doors. Why do they turn on automatically as soon as we go in? This is because the automatic door sensor is installed on the automatic door. When the automatic sensor detects someone approaching, it will control the door to open. What is the sensing range of the automatic door sensor?

Microwave automatic door sensor: microwave automatic door sensor is also called microwave radar. Microwaves can detect moving objects and react quickly. This kind of microwave automatic door sensor is suitable for places with slow pedestrian speed. But when the people near the door are still, the microwave detector will judge that there is no one and close the door. So it could get caught.

Infrared automatic door sensor: infrared will react to organisms with heat source, so whether pedestrians move or not, as long as they stay in the detection range of infrared automatic door sensor, they will keep the door open. But the response speed of infrared automatic door sensor is slower than that of microwave automatic door sensor.

The automatic door sensor has a fixed sensing range. People beyond this range will not affect it, so it will not be open all the time, because there are always people coming and going at the door. The sensing range of the automatic sensor is generally within the circular range of 5 meters in diameter. The closer to the center, the stronger the perception. When installing the automatic door sensor, pay attention to the position of the detection head, otherwise the detection range will be affected. The sensitivity of the automatic door sensor can also be adjusted.

Automatic door sensor generally has seven components, namely belt tension pulley component, terminal frame device, power beam, universal adjustable hanger, microcomputer intelligent control system, power device and belt component. When wiring, the original wiring should be inserted into the inductor. There is a socket on the sensor, which can be inserted well. Then connect the other end of the line to the other end of the terminal. Pay attention to the color of the wire when connecting. The same color is the signal line, different color is the power line. After the automatic door sensor is installed, it shall be fixed on the door frame, and the height from the ground shall not be less than 2.5m.
