Smart Motion Sensors — PIR Detectors in Tbilisi
Smart Motion Sensors (Smart PIR Detectors) are wireless IoT devices that detect human movement using infrared (PIR - Passive Infrared) technology and instantly send notifications to your smartphone, create automation scenarios (automatic lighting activation, alarm triggering) and integrate with smart home ecosystems (Alexa, Google Home, HomeKit) in Tbilisi and throughout Georgia. These sensors provide security (unauthorized entry notification), energy efficiency (automatic lighting shutoff when nobody in room), comfort (lighting turns on when you enter room) and monitoring (activity history), making them ideal for residential houses, apartments, offices, shops, warehouses and any type of facilities where motion detection and automation is needed. LAGI offers full range of smart motion sensors: Wi-Fi sensors (direct router connection, no hub needed), Zigbee sensors (low power consumption, mesh network, hub required), Z-Wave sensors (900MHz frequency, long range), 360° sensors (ceiling installation, full coverage), 120° sensors (wall installation, directional detection), pet-immune sensors (ignore pets <15kg), battery sensors (CR2450, 1-2 year lifespan), USB powered sensors (no battery replacement needed). All sensors compatible with Alexa, Google Home, HomeKit, Home Assistant ecosystems.
Main Types of Smart Motion Sensors
- 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.
- 360° sensors — ceiling installation, full 360° coverage, detect motion in all directions, 6-8m range, ideal for rooms, corridors, common spaces.
- 120° sensors — wall installation, directional 120° coverage, 8-12m range, ideal for corridors, stairs, entrances where directional detection needed.
- Pet-immune sensors — ignore pets <15kg (dogs, cats), detect only humans, prevent false alarms, ideal for homes with pets.
- Battery sensors — CR2450 battery, 1-2 year lifespan, low battery notification, wireless installation, most common type, ideal for any location.
FAQ — Frequently Asked Questions
Smart motion sensor uses PIR (Passive Infrared) technology that detects infrared radiation (heat) emitted by human body. How it works: 1) PIR sensor — contains pyroelectric crystal that reacts to infrared radiation. 2) Fresnel lens — focuses infrared radiation on sensor and creates detection zones. 3) motion detection — when person moves in sensor's field of view, infrared radiation changes and sensor detects motion. 4) signal transmission — sensor instantly sends signal to hub or directly via Wi-Fi. 5) notification and automation — hub sends notification to smartphone and executes scenarios (e.g. turns on lighting). Important: PIR sensor detects only motion, not static objects. If person stands still, sensor won't detect.
360° sensors (ceiling installation) — full 360° coverage in all directions, detect motion in entire room, 6-8m range, ideal for rooms (bedroom, living room, kitchen), common spaces, offices where full coverage needed. Installation: center of ceiling, 2.4-3m height. 120° sensors (wall installation) — directional 120° coverage (cone shape), detect motion in specific direction, 8-12m range, ideal for corridors, stairs, entrances, garages where directional detection needed. Installation: on wall, 2-2.5m height, pointed toward where motion should be detected. Recommendation: 360° — rooms, common spaces. 120° — corridors, stairs, entrances.
Smart motion sensors allow creating multiple automation scenarios: 1) automatic lighting — lighting on when you enter room, lighting off after 5 minutes if no motion detected, lighting dimming at night (30% brightness). 2) security — smartphone notification when motion detected in your absence, alarm activation, camera recording start. 3) energy efficiency — HVAC shutoff if nobody in room for 30 minutes, electrical devices shutoff. 4) comfort — music on when you enter living room, night lighting on stairs. 5) monitoring — activity history (what time was motion), elderly monitoring (notification if no motion for 12 hours). 6) scenarios — "movie mode" (no motion detected → lighting doesn't turn on). All scenarios created in smartphone app.
