Dual-Sense™ Motion Detection
Two technologies. One intelligent response.
Combine the precision of PIR with the sensitivity of microwave (HF) detection. Dual-Sense™ brings reliable, adaptable motion sensing to any lighting control system.
Why Combine Two Detection Technologies?
Smarter lighting begins with smarter sensing
In intelligent lighting systems, motion detection plays a critical role — not only in enhancing user comfort but also in optimizing energy efficiency.
Today, two core technologies dominate the market:
Microwave (HF) – known for its high sensitivity and broad coverage
Passive Infrared (PIR) – valued for its accuracy and stability in defined zones
Each has strengths. Each has limitations.
Relying on just one sensing method often leads to compromises — either in performance, reliability, or flexibility.
That’s why the future of smart lighting calls for a more integrated approach.
Microwave (HF) Detection
Ultra-sensitive motion sensing for wide-area coverage
HF detection uses high-frequency electromagnetic waves to sense movement — even through certain materials. This makes it extremely responsive, ideal for both open and partially obstructed spaces.
Key Advantages：
Detects even the smallest or micro-movements
Can be fully enclosed within light fixtures
Delivers broad coverage without direct line-of-sight
Metal Reflection Interference
Waves bounce off metallic surfaces, creating false triggers.
Environmental Motion Sensitivity
Moving fans or curtains can be misinterpreted as human movement.
Signal Penetration Across Zones
Detects people in adjacent rooms or corridors through walls.
Passive Infrared (PIR) Detection
Precise, heat-based motion sensing for defined areas
PIR detection identifies changes in infrared radiation — typically emitted by human body heat — to detect movement within a defined zone. It is highly accurate and stable, making it ideal for targeted, privacy-conscious applications.
Key Advantages：
Accurate detection based on body heat
Immune to interference from fans, air conditioning, or airflow
Ideal for personal or clearly defined detection zones
Sunlight & Heat Interference
Strong sunlight or nearby heat sources can cause false triggers.
Obstruction Blind Spots
Objects like furniture or glass can block detection zones, leading to missed motion.
Low-Temperature & Slow-Movement Misses
Cold environments or very slow movement may go undetected.
No single method fits all.
That’s where Dual-Sense™ comes in — intelligently combining both.
💡 Enter Dual-Sense™
Hytronik’s Dual-Sense™ blends Microwave and PIR sensing into one cohesive solution. You can even choose which one (or both) to use — either manually or automatically.
Result? Smarter, more adaptable detection across all spaces.
From open-plan offices to echo-heavy stairwells, your lights won’t turn on too easily — or worse, not at all.
Four Detection Modes for Any Scenario
Dual-Sense™ technology combines both HF and PIR sensing, offering 4 selectable detection modes — fine-tuned for different environments and user needs.
Four Modes：
HF Only – Super-sensitive mode for maximum responsiveness — detects even micro-movements across large areas.
PIR Only – High-precision and privacy-focused — responds only to body heat within defined zones.
Either – Triggered by either HF or PIR for maximum coverage and responsiveness.
Both – Activates only when both HF and PIR detect motion — ensuring highest accuracy and avoiding false triggers.
Three Easy Setup Methods
Choose and configure your preferred detection mode effortlessly, keeping learning curves low and flexibility high.
DIP Switch – On-device hardware setting for quick and reliable adjustments.
Remote Controller – Make changes from the ground without accessing the fixture.
Koolmesh App – featured wireless control and advanced configuration via your smartphone/pad.
🛠️ Real Talk: Why It Matters
Installers and building managers, rejoice.
Dual-Sense™ means:
🔧 Fewer callbacks from annoyed users
⏱️ Faster commissioning (especially in complex spaces)
🎛️ Flexibility to adapt with DIP switches or software
