A comprehensive guide to different types of door sensors
When it comes to commercial sliding doors, optical sensors, and motion sensors are commonly employed for enhanced security. Optical sensors, in particular, are widely popular for their effectiveness.
Positioned atop doors or at door corners, these sensors feature antennas directed toward the entrance to ensure optimal functionality. The use of optical sensors provides reliable detection, contributing to the overall safety and efficiency of commercial sliding door systems. Safety sensors in automatic door (cảm biến an toàn mở cửa tự động) are also a good choice for you, they operate equivalent to the optical sensors or motion sensors.
Motion sensors are commonly used for automatic doors, as they offer convenience, security, and energy efficiency
Infrared sensors
Infrared sensors offer a distinct advantage over optical door sensors due to their ability to detect movement even when a person is stationary in front of the door. Triggered by changes in thermal energy within their line of vision, these sensors, commonly known as Passive Infrared (PIR) sensors, are particularly efficient.
When a person walks across the sensor’s line of vision, the change in temperature, often attributed to body heat, prompts the sensor to signal the door to slide open.
What sets PIR sensors apart is their customization capability. Users can program them to ignore minor changes in temperature, preventing, for instance, the door from opening if a pet attempts to exit. The compact form factor of these sensors makes them easily adaptable for use within homes, offering a reliable and versatile solution for automated door systems.
Pressure sensors
Pressure sensors, although somewhat considered archaic, operate by utilizing a pressure mat positioned in front of the door. When the pressure mat detects a predefined amount of pressure, it sends a signal to the door to open. This type of sensor allows for a degree of customization, allowing users to set a specific pressure threshold.
However, pressure-based sensors have their limitations. For instance, if a person stands on the pressure mat for an extended period, the door equipped with this sensor may remain open. Despite their historical use, the drawbacks associated with pressure sensors have led to the development and adoption of more advanced technologies, such as infrared and motion sensors, for improved reliability and functionality in automated door systems.
One of the advantages of using pressure sensors for door control is that they can be integrated with other smart devices, such as smoke detectors, to create smart home automations. For example, you can use an Aqara smart smoke sensor (cảm biến khói thông minh Aqara) to detect fire by sensing smoke. If the smoke concentration reaches a certain threshold, the smoke sensor will sound an alarm and send a notification to your phone. It can also trigger the pressure sensors on your doors to open them automatically, allowing you to escape or let the firefighters in.

Circuit-based or contact sensors
Contact sensors, also known as circuit-based sensors, operate differently from the previously mentioned types. These sensors provide alerts when a door is opened, signaling the homeowner in the event of a breach.
Thanks to their effectiveness in home and garage security, circuit-based sensors are often considered the preferred choice. Their ability to detect door openings and breaches makes them a reliable option for enhancing the security of residential spaces.
These door sensors are compact and can be easily affixed to the top of your front door or patio door. The added benefit is that some of these door sensors are smart, offering integration with other smart devices such as security cameras or smart lights.
Acoustic sensors
Acoustic sensors, commonly known as sound sensors, are designed to identify specific sounds or noises associated with potential threats. These sensors can be programmed to recognize various sounds, such as breaking glass, loud bangs, or the distinct noise of a door being forcefully kicked in.
The inclusion of acoustic sensors in a door alarm system proves valuable, as they have the capability to detect threats that might go unnoticed by other sensor types. By actively listening for particular sounds, these sensors add an extra layer of security, ensuring that homeowners receive timely alerts to potential dangers.
Through the integration of these diverse sensor types, you can establish a comprehensive door alarm system that delivers peace of mind and robust protection for your home.

In summary, door alarm sensors constitute a crucial element in any comprehensive security system. Available in various types, each with its distinct features and advantages, these sensors cater to different security requirements. The choice of door alarm sensor depends on individual security needs and preferences
