What are the import and export equipment in supermarkets?

Supermarket entry and exit systems, especially those automatic induction doors, typically come in two types: infrared sensing and radar sensing. Each type works differently and has its own unique setup. 1. Infrared Sensing: These doors usually have a slim barrier post in front of the main pillar where the swinging mechanism is located. Inside this barrier post, there’s a sensor. On one side of the door, you’ll find an infrared emitter, while on the opposite side, there’s a reflector, similar to a bike tail light. When the system is activated, the red light from the emitter hits the reflector, creating a closed circuit. As soon as a customer walks past, the infrared beam gets interrupted, triggering the sensor in the main pillar and sending a signal to open the door. 2. Radar Sensing: With radar-sensing doors, it often seems like there's no barrier in front because the sensor is directly mounted on the main pillar. This creates an invisible detection zone roughly one meter in front of the door. No matter if you're walking straight toward the entrance or approaching from the side, as long as you step into this sensing area, the door will automatically detect your presence and open. It’s highly convenient, especially when multiple people are moving around at once. Both types of sensors are designed to make shopping more seamless and accessible. Infrared sensors work best in environments where precise alignment is possible, ensuring a smooth opening experience. Radar sensors, on the other hand, offer broader coverage, making them ideal for high-traffic areas. Depending on the supermarket's design and layout, either option can enhance customer convenience and improve overall efficiency. I’ve seen both types being used in various stores, and each has its own advantages depending on the specific needs of the space.
