Smart Human Presence Sensors — mmWave Radar Detectors in Tbilisi
Smart Human Presence Sensors (mmWave Radar Sensors) are advanced IoT devices that use millimeter wave (mmWave) radar technology to detect human presence and detect not only motion but also static people, breathing and small movements, making them ideal for automation where traditional PIR sensors fail in Tbilisi and throughout Georgia. These sensors provide 100% accuracy (won't turn off lighting if person sits still), energy efficiency (lighting/HVAC turns off only when room truly empty), comfort (lighting never turns off mid-work) and monitoring (real-time presence status), making them ideal for residential houses, offices, conference rooms, libraries, hospitals and any type of facilities where people often sit still or work. LAGI offers full range of smart human presence sensors: 24GHz mmWave sensors (high accuracy, detect breathing), 60GHz mmWave sensors (ultra-high resolution, position tracking), Wi-Fi sensors (direct router connection), Zigbee sensors (low power consumption, mesh network), multi-zone sensors (detect how many people in room), distance monitoring sensors (precise distance to person), battery sensors (wireless installation), USB powered sensors (constant power). All sensors compatible with Alexa, Google Home, HomeKit, Home Assistant ecosystems.
Main Types of Smart Human Presence Sensors
- 24GHz mmWave sensors — millimeter wave radar, detect breathing and small movements, 5-8m range, detect static people, ideal for bedrooms, offices, conference rooms.
- 60GHz mmWave sensors — ultra-high resolution, position tracking (X, Y coordinates), detect how many people and where they are, 8-12m range, ideal for large rooms, smart offices.
- Wi-Fi sensors — direct Wi-Fi router connection (2.4GHz), no hub needed, smartphone app, instant notifications, adjustable sensitivity, ideal for small homes.
- Zigbee sensors — low power consumption, mesh network, hub required (Zigbee hub/gateway), battery 1-2 years, fast response <1 second, ideal for large homes, multiple sensors.
- Multi-zone sensors — detect how many people in room (1-10 people), zone division (e.g. work zone, rest zone), ideal for open-space offices, conference rooms.
- Distance monitoring sensors — precise distance to person (0.5-8m), position tracking, ideal for bed monitoring (elderly), desk presence detection.
FAQ — Frequently Asked Questions
PIR (Passive Infrared) motion sensors — detect only motion through infrared radiation change, don't detect static people, lighting turns off if person sits still 5-10 minutes, problem in offices (person sits at computer → lighting turns off), conference rooms (people listen to presentation → lighting turns off). mmWave human presence sensors — use millimeter wave radar, detect breathing and small movements, detect static people, lighting never turns off if person in room (even if sitting still), 100% accuracy, ideal for offices, conference rooms, libraries. Recommendation: PIR — corridors, stairs (where people move). mmWave — offices, conference rooms, bedrooms (where people sit still).
mmWave (millimeter Wave) radar sensor uses millimeter wave radio waves (24GHz or 60GHz frequency) to detect human. How it works: 1) radar transmission — sensor sends millimeter wave radio waves into room. 2) reflection — waves reflect from objects (human body, walls, furniture) and return to sensor. 3) Doppler effect — when person moves or breathes, reflected wave frequency changes (Doppler effect), sensor detects this change. 4) signal processing — sensor processes reflected signals and determines: is person in room, how many people, where they are (distance, position), what they're doing (moving, sitting, lying). 5) automation — sensor sends signal to hub and executes scenarios (e.g. turns on lighting). Advantage: detects static people, breathing, small movements, 100% accuracy.
Smart human presence sensors allow creating advanced automation scenarios: 1) automatic lighting — lighting on when person enters room, lighting stays on while person in room (even if sitting still), lighting off only when room truly empty. 2) energy efficiency — HVAC shutoff when nobody in room for 30+ minutes, electrical devices shutoff, energy savings 30-50%. 3) comfort — lighting never turns off mid-work (no more "waving hands" for PIR sensor), music on when you enter room. 4) security — smartphone notification when person detected in your absence, camera recording start. 5) monitoring — real-time presence status (how many people in office), elderly monitoring (notification if no activity for 12 hours). 6) smart office — desk presence detection (occupied/free), automatic conference room booking.
