True Presence Sensors | Advanced 24GHz Radar Detection by TRUEiSENSE

Author : Trueisense 764 | Published On : 05 Aug 2026

Quick Answer

A true presence sensor goes beyond conventional motion detection by utilizing 24GHz FMCW radar and mmWave technology to detect subtle human breathing and micro-vibrations. It answers the critical question: 'Is a living human being in this space right now?' rather than just 'Has anyone moved recently?'. Engineered by TRUEiSENSE, a leading Indian manufacturer of advanced automation, these sensors guarantee zero "false-off" interruptions for stationary occupants in corporate offices and healthcare facilities, seamlessly slashing energy consumption by 40% to 80%.

Introduction

Indian corporate offices waste crores of rupees every year illuminating empty meeting rooms and executive cabins. When businesses attempt to solve this with standard PIR motion sensors, they often encounter a frustrating new problem: the lights switch off on executives or employees simply because they are sitting still while typing or reading.

Upgrading to True Presence Sensors permanently resolves both the immense energy waste and the workplace frustration. By sensing the subtle vibrations of the human body with nano-sensing technology, these advanced detectors ensure optimal energy efficiency in real time without plunging stationary workers into darkness. As a dedicated manufacturer of industrial and commercial automation, TRUEiSENSE designs non-invasive, high-precision radar solutions that enhance smart building automation, improving comfort while significantly reducing energy consumption.

Benefits

Swapping out outdated motion detectors for TRUEiSENSE true presence sensors provides immediate, tangible advantages for enterprises:

Zero False-Offs (Breathing Detection): The sensor doesn't just detect entry; it continuously confirms presence through breathing and micro-vibrations even during complete stillness, eliminating frustrating shut-offs.
Massive Energy Savings (40–80%): By optimizing power usage and activating lights only when required, true presence sensing reduces energy consumption significantly.
Seamless IoT Integration: Effortlessly integrates with IoT and BMS platforms for centralized monitoring and intelligent building automation.
Privacy-Preserving: Provides non-invasive radar sensing that requires no cameras, captures no images, and collects no personal data.
Real-Time Analysis: Instantly detects micro-movements with unmatched accuracy for seamless automation and smarter, data-driven decision-making.

Applications

To get the absolute most out of your investment, install true presence sensors in environments where occupants remain stationary for extended periods:

In Smart Office Spaces: Automatically adjust lighting, HVAC, and electronic devices based on presence, creating an energy-efficient, comfortable, and productive environment.
In Conference Rooms and Meeting Cabins: Lights, projectors, and AV systems power up as soon as attendees enter, enhancing productivity and ensuring no energy is wasted when the room is empty.
In Healthcare Facilities: In patient rooms, diagnostic areas, and hallways, true presence sensing ensures lighting and equipment activate only when needed, promoting energy savings without compromising patient care.
In Elevators and Lift Lobbies: Automatically activate lighting and air circulation when passengers are present, ensuring energy efficiency and a pleasant waiting experience.

Buying Guide: Choosing True Presence Technology

Not all sensing technologies serve the same purpose. Follow these guidelines to ensure you select the right true presence infrastructure:

Step 1 — Verify the Occupancy Pattern: Ask yourself if the space involves stationary or movement-based occupancy. If occupants sit at desks or conference tables, you strictly require a True Presence Sensor (Radar + Breathing Detection).
Step 2 — Select the Technology: Ensure the product operates on 24GHz FMCW Radar or mmWave technology, as this is the only standard that accurately detects stationary occupants without being affected by ambient temperature shifts.
Step 3 — Evaluate Advanced Features: Look for systems that offer programmable LUX and time-delay settings, as well as a 360° detection range to ensure no blind spots across the entire zone.
Step 4 — Schedule a Professional Assessment: For large, multi-zone office installations, schedule a Free Energy Savings Assessment to get detailed recommendations and a customized ROI estimate.

Installation and Usage Tips

Ensure peak performance and seamless automation by following these expert implementation practices:

Always deploy True Presence sensors (like the Crux or Wave Detector) for desk and seated work environments—never use standard PIR motion sensors, as they will switch off on stationary occupants.
Utilize the programmable LUX thresholds to harness daylight harvesting, ensuring artificial lights only activate when natural ambient light falls below your configured levels.
For highly critical areas like hospital diagnostic rooms, rely on responsive true presence systems to provide optimal lighting and functionality, reducing waste while enhancing operational care.
Prior to widespread facility deployment, utilize TRUEiSENSE's Interactive Sensor Lab to experience real-time sensing simulation and compare smart detection capabilities.

FAQ

Q: What is a True Presence Sensor?

A: It is an advanced sensor utilizing 24GHz FMCW radar and mmWave technology to detect actual human presence through subtle breathing patterns and lung vibrations, eliminating the false triggers common in traditional motion sensors.
