Over the years, automatic door technology has evolved dramatically, transforming from simple mechanisms to intelligent systems equipped with advanced sensors and customization options. This blog traces the technological evolution of automatic doors, exploring how they’ve advanced to meet modern demands.

The First Automatic Doors

Automatic doors originated in the mid-20th century, with simple designs focusing on ease of entry for large crowds in commercial spaces.

• Manual Assistance and Basic Activation: In the early stages, automatic doors were activated by pressure plates or basic motion detection. Users had to step on a floor plate to trigger the door’s opening mechanism. This method was simple but effective, allowing high volumes of people to enter and exit seamlessly.
• Limited Applications: Early automatic doors were primarily used in high-traffic commercial spaces such as hotels, airports, and department stores. However, limited technology and high costs restricted their widespread adoption.

The Sensor Revolution

With advancements in sensor technology in the 1960s and 1970s, automatic doors evolved beyond floor plates to more sophisticated detection methods.

• Infrared Sensors: Infrared sensors detect heat signatures within a specified range. Early infrared systems triggered the door to open when they sensed an approaching individual’s body heat. This innovation helped improve accessibility by removing the need for direct physical interaction with the door.
• Microwave Motion Sensors: Microwave sensors detect movement by emitting radio waves and analyzing their reflection from objects in the detection zone. Microwave technology allowed doors to respond to an approaching person quickly and reliably, reducing wait times and providing a smoother entry experience.

The Era of Customization and User Control

As automatic door technology advanced in the 1980s and 1990s, manufacturers introduced options for greater customization and control.

• Programmable Settings: Door systems became programmable, allowing business owners to control the door’s opening and closing speeds, delay times, and sensitivity. This customization provided options for tailoring door behaviour to specific times of day, enhancing energy efficiency by limiting door openings during non-peak hours.
• Enhanced User Control: Remote control options allowed facilities managers to override door settings or shut doors remotely, providing better security and operational control. These programmable doors were especially beneficial in hospitals, airports, and other high-security or regulated environments.

Advanced Sensors and Smart Integration

The early 2000s marked a turning point with the advent of intelligent systems, making automatic doors smarter and more adaptive.

• Multi-Sensor Integration: Automatic doors began using a combination of sensor types—infrared, microwave, and ultrasonic—to improve accuracy and safety. Multi-sensor doors could detect the size, speed, and movement direction of approaching individuals, minimizing false triggers from passing pedestrians.
• Safety Features and Accessibility: Advanced systems incorporated fail-safe mechanisms, such as automatic retraction if an obstruction is detected, to prevent accidents. Doors also began to include ADA-compliant features like adjustable opening force, further enhancing accessibility for individuals with mobility aids.
• Climate-Sensitive Technology: Doors with climate-sensitive sensors could detect outdoor temperature changes and adjust opening width to conserve energy. This feature became popular in regions with extreme weather conditions, where maintaining indoor climate was critical to reducing energy consumption.

AI and IoT-Enabled Doors

In recent years, automatic door technology has embraced artificial intelligence (AI) and the Internet of Things (IoT), making today’s systems highly adaptable and connected.

• AI-Driven Doors: AI-powered doors can analyze traffic patterns, predict peak times, and adjust their behaviour accordingly. This data-driven approach allows businesses to optimize door use and reduce energy costs by minimizing unnecessary openings. AI can also predict maintenance needs based on door usage, preventing unexpected downtime.
• IoT Integration for Building Management: IoT-enabled doors connect to centralized building management systems, allowing facility managers to monitor door activity and make adjustments remotely. IoT technology also enables real-time monitoring of door performance, alerting staff to potential issues before they lead to system failures.
• Facial Recognition and Biometric Access: Biometric access, such as facial recognition and fingerprint scanning, has become more prevalent in security-focused facilities. These technologies enhance entry security, providing personalized access while minimizing physical interaction with the door.
