Introduction

In today’s world of smart automation, intelligent spaces are no longer a luxury — they’re a necessity. As energy efficiency, occupant comfort, and automation become top priorities in both residential and commercial infrastructure, the foundation of these solutions rests on one core technology: presence detection.

TRUEiSENSE is proud to lead this innovation with a cutting-edge presence sensing ecosystem, redefining how buildings think, sense, and respond to human occupancy. From HVAC to lighting control, we introduce a smarter, more human-centred way to manage environments.

What Is a Presence Sensor?

At its simplest, a presence sensor detects whether someone is present in a room or space. Unlike basic motion sensors, which react to movement, true presence sensors are capable of recognizing stationary humans — ensuring lights or HVAC systems stay on when people are present, and turn off only when the space is genuinely empty.

This is where real presence sensors stand apart. Traditional Passive Infrared (PIR) sensors often fail to detect occupants who are sitting still, like someone working at a desk or reading. The result? Lights flick off, air conditioning stops, and frustration builds.

Transforming HVAC Systems with Real-Time Occupancy

Most HVAC systems rely on schedules or motion sensors. But real life doesn’t follow a rigid schedule. Meetings run late, people skip lunch, or they just sit quietly working.

With TRUEiSENSE’s real presence sensors, HVAC systems respond only when someone is truly in the room. This eliminates unnecessary heating or cooling, improving both energy savings and occupant comfort.

A mid-sized office building retrofitted with TRUEiSENSE technology saw HVAC energy use drop by over 40%, with no compromise in comfort, simply by aligning operations with actual presence.

Offline Voice Control with “Hello ‘T’”

At TRUEiSENSE, we don’t stop at sensors. We’ve developed the Hello ‘T’ offline voice controller — a privacy-respecting voice assistant that works completely offline.

Unlike cloud-based assistants that rely on constant internet access, Hello ‘T’:

• Works even without Wi-Fi
• Does not record or send data externally
• Offers lightning-fast command processing
• Seamlessly integrates with HVAC, lighting, curtains, and more

Voice + Presence fusion means the system knows who’s in the room and what they want, without needing touchscreens or apps.

Example:
A user walks into a room, and the system senses their presence. Without the internet, they say:

“Hello T, set the temperature to 22 degrees.”
Instantly, the room responds — no lag, no cloud, no privacy concerns.

Smart Building Applications Across Sectors

TRUEiSENSE solutions fit a wide array of applications:

• Homes: Personalised comfort, voice-controlled automation, energy savings
• Offices: Efficient zone management, smart scheduling, presence analytics
• Hospitals: Monitoring patient presence without intrusion, reducing energy waste
• Warehouses and factories: Automating lighting/HVAC in areas with intermittent occupancy

In elderly care facilities, presence sensors can alert staff if a resident has not moved for a concerning period, without cameras or invasive monitoring.

Energy Savings and Environmental Impact

With increasing energy costs and climate targets, smart automation isn’t just convenient — it’s necessary. RealPresence sensors deliver:

• Lower operational costs
• Reduced carbon footprint
• Increased equipment life (by operating only when needed)

According to field tests, buildings equipped with TRUEiSENSE presence sensors and “Hello ‘T’” voice control reported up to a 40% drop in energy consumption, with ROI achieved in under 18 months.

Why Choose TRUEiSENSE?

• Privacy-First Design: No cameras, no cloud dependency, full offline control
• High Accuracy: Real presence, not just motion
• Modular and Scalable: Fits small apartments to large buildings
• AI-Driven: Learns occupant behaviour to optimise response
• Seamless Integration: Works with existing HVAC and lighting infrastructure

We empower smart environments that are not only intelligent but also respectful of user data and behaviour.

Conclusion
