In today’s fast-paced environments—whether in retail stores, hospitals, office buildings, or transportation hubs—automatic doors play a critical role in enabling safe, convenient, and touch-free entry. One of the core technologies powering these systems is the microwave sensor. So, how do microwave sensors in automatic doors function? Let’s explore their technology, advantages, and applications. What Is a Microwave Sensor? A microwave sensor is a type of motion detector that uses Doppler radar technology to detect moving objects. Unlike infrared sensors that rely on temperature differences, microwave sensors emit high-frequency electromagnetic waves (usually around 24.125 GHz or 5.8 GHz) and analyze the reflected signals. When an object—such as a person—moves within the detection zone, it causes a change in the frequency of the reflected waves (the Doppler effect), which triggers the sensor to send a signal to open the door. How Microwave Sensors Work in Automatic Doors Here’s a step-...

Automatic door sensors are a crucial component in modern access systems, providing seamless entry and exit in commercial buildings, healthcare facilities, transportation hubs, and retail spaces. One common question from facility managers and building owners is: "How long does an automatic door sensor typically last?" In this article, we’ll explore the typical lifespan of an automatic door sensor, the factors that affect its longevity, and how to maximize its operational life. Typical Lifespan: 5 to 10 Years Under normal usage and conditions, a high-quality automatic door sensor can last anywhere from 5 to 10 years. However, this estimate depends on several key variables including: Sensor type (infrared, microwave, or dual-technology) Operating environment Installation quality Maintenance frequency Traffic volume and usage patterns Factors That Influence Sensor Lifespan 1. Sensor Technology Different types of sensors have varying durability: Infrared Sensors (Passive/Active):...

Automatic doors have become a staple in commercial, healthcare, and retail environments, offering convenience, accessibility, and energy efficiency. However, when an automatic door sensor fails to detect motion, it can disrupt traffic flow, frustrate users, and potentially compromise safety. In this article, we’ll explore the most common reasons why your automatic door sensor may not be detecting motion—and how to troubleshoot them. 1. Sensor Obstruction or Dirt Buildup One of the most frequent causes of motion detection failure is physical blockage or dirt accumulation on the sensor lens. Dust, spider webs, water stains, or stickers can interfere with the sensor’s ability to recognize motion accurately. Solution: Gently clean the sensor lens using a microfiber cloth. Ensure no signage, objects, or decorations are blocking the sensor’s line of sight. 2. Incorrect Sensor Settings Modern motion sensors often come with adjustable settings, including: Detection range Sensitivity Activation...

Public transportation stations—such as subway platforms, train stations, and bus terminals—are high-traffic areas that demand efficiency, safety, and accessibility. To meet these operational and safety standards, automatic door sensors have become an essential technology in such environments. But how are they used, and why are they so important? The Role of Automatic Door Sensors Automatic door sensors are devices that detect movement, presence, or other environmental changes to trigger the opening or closing of doors. In public transportation stations, these sensors are used in a variety of ways: 1. Platform Screen Doors (PSDs) In metro and subway systems, platform screen doors are often installed to enhance safety by separating passengers from moving trains. These doors rely on precision sensors to ensure they only open when a train has arrived and aligned properly. Sensors help detect: The exact position of the train Passenger movement near the doors Obstructions that may prevent s...
