View DetailsOur mmWave radar presence sensors detect true human presence — including a guest sitting still or sleeping — so a presence sensor never falsely reports a room as vacant. Hotel room status, housekeeping, and HVAC stay accurate.
50,000 presence sensors per month with controlled capacity and process discipline for repeat hotel orders.
Every presence sensor passes in-process inspection, first-article report, and final outgoing inspection. CE, FCC, RoHS, ISO 9001 certified.
Presence sensors shipped FOB Shenzhen, CIF, or DDP to 6 export markets (US, Germany, UK, Japan, UAE, Vietnam) with full documentation.
Zigbee, WiFi, and Matter over Thread presence sensors — interoperable with Tuya, Apple Home, Google Home, and Alexa ecosystems.
A mmWave presence sensor is a radar-based human detection device that senses presence — including micro-motion such as breathing — up to 2.5 meters, with no cameras and no false alarms from a still guest. Unlike PIR sensors, which register anyone reading in bed as “vacant” after 30 seconds of stillness and waste 20–40% of HVAC energy on rooms guests stepped out of, mmWave presence detection keeps a room marked occupied for the entire stay and flips to vacant only when both ceiling sensors (bedroom and bathroom) detect no micro-motion past the timeout.
For hotels and smart buildings this yields accurate housekeeping signals, real HVAC energy savings, and reliable occupancy analytics for revenue management. The same platform covers offices, meeting rooms, and bathrooms, so one hardware line supports an entire building automation project — all without cameras or wearables, preserving guest privacy.
Five mmWave presence sensors — pick the model and protocol that match your gateway and form factor. Three ceiling models share the same hardware platform (24 GHz wideband radar, 2.5m micro-motion, breathing sensitivity); the 60GHz and wall-mount models add a higher-resolution core and a retrofit form factor.
10+ years building presence sensors, 6+ export markets, 24h response, and full OEM/ODM support. Every presence sensor is backed by CE, FCC, and RoHS compliance.
Common questions about our mmWave presence sensors — detection range, protocol, installation, and OEM/ODM terms.
A presence sensor is a device that detects whether a person is in a room, even when the person is sitting still or asleep. Unlike a motion sensor (PIR), which only reacts to large movement, a presence sensor uses mmWave radar to sense micro-motion such as breathing and chest movement — so it never falsely reports an occupied room as vacant. Read our in-depth guide for the full mechanism.
A mmWave presence sensor emits 24 GHz radio waves and reads the reflections to detect human micro-motion — chest movement, gestures, and even breathing. The sensor processes the signal in real time to report occupied or vacant room status, with adjustable sensitivity and detection range up to 2.5 meters. See our technical guide for the full signal-processing breakdown.
PIR sensors only trigger on large motion and miss stationary occupants — they often report a sleeping guest or a person reading as vacant. mmWave presence sensors detect micro-motion including breathing, so they report true occupancy. For hotel rooms, smart offices, and bathrooms where a stationary person matters, mmWave is the right choice. Our detailed comparison covers the seven criteria buyers evaluate.
Common use cases include hotel room occupancy (energy saving, housekeeping status, do-not-disturb logic), smart offices (lighting and HVAC tied to real presence), bathrooms (auto light and fan), meeting rooms, and any space where knowing true occupancy matters more than detecting motion. See our hotel occupancy solution for a hospitality roll-out example.
Zigbee and Matter are best for low-power mesh networks in hotels and large offices (no hub rewiring, battery-friendly). Wi-Fi is simpler for residential or small deployments where you already have strong Wi-Fi coverage. Our ceiling presence sensor ships in all three protocols so you can match your existing gateway without replacing infrastructure. Start with the Zigbee model for the most common hotel deployment.
We are the OEM/ODM manufacturer — every presence sensor is designed and built in-house at our Shenzhen facility. You buy direct from the factory, with full support for custom firmware, branding, and packaging for hotel or commercial rollouts. See our hotel solution for a real-world deployment, or contact us for sampling (3-5 days) and mass production (7-10 days).
