The EAE Technology PD100 Sensor: A Comprehensive Guide to Intelligent Presence and Lighting Control

In the modern landscape of building automation, efficiency, comfort, and energy savings are paramount. EAE Technology, a leading provider of smart building solutions, addresses these needs with its highly versatile PD100 presence sensor. Designed as a core component of KNX-based intelligent systems, the PD100 combines sophisticated presence detection with constant light control, making it an indispensable tool for optimizing the performance of various indoor spaces, from large offices and conference rooms to classrooms and corridors. This detailed overview explores the sensor’s core technology, its wide-ranging applications, and the tangible benefits it delivers.

Core Technology and Operating Principle

At the heart of the PD100’s functionality is its dual-sensor design, which integrates both a passive infrared (PIR) movement sensor and an integrated light level sensor. This combination allows the device to not only detect the presence of individuals but also to measure the ambient light, enabling it to perform its signature constant light function. The PIR sensor operates by detecting infrared radiation emitted by moving bodies, while the light sensor continuously monitors the brightness in the surrounding area.

The PD100’s intelligence lies in its ability to process data from both sensors to maintain a user-defined light level. When a person enters a room, the movement sensor detects their presence. The device then activates the lighting system if the ambient light is below the set threshold. Once activated, the constant light function kicks in, dynamically adjusting the light output (dimming or brightening) to compensate for changes in natural light (e.g., sunlight from a window), ensuring the illumination remains at a consistent, optimal level. This prevents unnecessary energy consumption by lights that would otherwise stay on at full brightness.

The sensor offers flexible configuration options, allowing users to define different brightness levels and durations for various states, such as “Movement,” “After Movement,” and “No Movement.” This level of granular control ensures that the lighting perfectly matches the activity and purpose of the space.

Design, Installation, and Integration

The PD100 is engineered for seamless integration into a variety of architectural designs. It is available in two models: flush-mounted and surface-mounted. This flexibility allows for a clean and discreet installation on ceilings, blending into the interior design of modern buildings. The recommended installation height ranges from 2.5 to 5 meters, with a typical detection diameter of 6 meters for a seated person and 7 meters for a walking person at a 2.5-meter height. The PD100 operates with a 360-degree detection angle, ensuring comprehensive coverage of the area below.

One of the most significant advantages of the PD100 is its KNX-based operation. It is powered directly by the KNX bus line, eliminating the need for an external power supply. This simplifies installation and reduces cabling complexity, which is a major benefit in large-scale building automation projects. The sensor can be configured to operate as a single, standalone device or as part of a master-slave setup in parallel with other KNX presence sensors. This master-slave capability is particularly useful for covering large, irregular, or interconnected spaces, as it allows multiple sensors to work together as a single, cohesive unit.

For added convenience during setup, the PD100 includes special test and calibration modes. These features allow installers to quickly and easily verify the sensor’s detection range and calibrate the light level sensor, streamlining the commissioning process and ensuring optimal performance from day one.

Versatile Applications and Real-World Impact

The EAE Technology PD100 is designed for a broad spectrum of indoor applications where intelligent control is crucial for energy management and occupant comfort. Its robust feature set makes it ideal for:

• Office Buildings: In medium to large-scale offices, the PD100 ensures that lighting and HVAC systems are active only when rooms are occupied. It can intelligently manage lighting for individual workstations or entire zones, automatically dimming lights on sunny days and switching them off in empty rooms, leading to substantial energy savings.
• Conference and Meeting Rooms: These spaces often see intermittent use. The PD100 can automatically activate presentation lighting and adjust HVAC based on occupancy, then revert to an energy-saving mode once the room is vacant.
• Classrooms: The sensor supports a comfortable learning environment by maintaining optimal lighting levels and adjusting ventilation, while also preventing energy waste when classes are not in session.
• Corridors and Hallways: With a customizable “Corridor Function,” the sensor can set different brightness levels for “Movement,” “After Movement,” and “No Movement” states, providing safety and visibility while minimizing energy use during periods of low traffic.
• Warehouses and Parking Garages: In these large, often sparsely occupied areas, the PD100 is a powerful tool for on-demand lighting. Lights can be set to activate in specific zones only when a presence is detected, drastically reducing the energy consumption compared to constant illumination.

Beyond Lighting: Integrated HVAC Control

While its primary function is lighting control, the PD100’s capabilities extend to other critical building systems. Thanks to a dedicated HVAC channel, the sensor can be linked to air conditioning and ventilation systems. This allows for a holistic approach to environmental control. For example, when presence is detected in a room, the PD100 can signal the HVAC system to begin heating or cooling the space. Conversely, when the room becomes vacant, the sensor can trigger the system to enter an energy-saving standby mode. This integration of lighting and climate control through a single, intelligent device maximizes both energy efficiency and occupant comfort.

Conclusion: A Smart Investment in Building Efficiency

The EAE Technology PD100 is more than just a simple sensor; it is a sophisticated, intelligent control device that provides a foundation for truly smart, energy-efficient buildings. By meticulously managing lighting and HVAC based on real-time occupancy and ambient conditions, it helps facility managers achieve significant reductions in energy consumption and operational costs. Its ease of installation, flexible configuration, and seamless integration with the KNX standard make it a standout choice for new construction and renovation projects alike. The PD100 represents a forward-thinking solution for creating spaces that are not only more sustainable but also more comfortable and responsive to the needs of the people who use them.
