Why choose a WiFi presence sensor for premium projects

The Ceiling Mount mmWave Human Presence Sensor (WiFi) is a WiFi presence sensor that detects true human presence — including a guest sitting still or sleeping — using 24GHz wideband mmWave radar. As a presence sensor, it gives specifiers what a basic presence sensor cannot: cloud-direct connectivity without a gateway, plus reliable occupancy detection for retrofit projects. This presence sensor even senses breathing-level micro-motion, so the presence sensor never falsely reports a room as vacant. As a WiFi presence sensor, it connects directly to the cloud without a gateway — making this presence sensor the fast path for retrofit hotel and apartment projects. The difference from the Zigbee presence sensor is the radio: this WiFi presence sensor for direct-to-cloud, the Zigbee presence sensor for whole-floor mesh deployments. For teams evaluating presence sensor options for retrofit tenders, this WiFi presence sensor is the de-facto reference for building automation projects that require presence sensor simplicity without dedicated gateway infrastructure.

Detection performance

Parameter	Value
Frequency band	24GHz (wideband)
Max motion detection	10m
Max micro-motion / static detection	2.5m
Breathing detection	Supported
Detection angle	120°

The 10m motion range covers large hotel rooms and meeting spaces from a single ceiling presence sensor. The 2.5m micro-motion range ensures a sleeping or seated guest is never missed — the presence sensor detects breathing, not just movement. Most mmWave presence sensors on the market detect micro-motion at only 1.5m or less; our presence sensor reaches 2.5m, covering the full bed area. The 120° field of view provides full room coverage when the presence sensor is ceiling-mounted. This WiFi presence sensor outperforms PIR presence sensors (which suffer high false-positive rates in summer when ambient temperature approaches body temperature) and standard 5.8GHz presence sensors in static-occupancy accuracy.

mmWave Presence Sensor vs PIR Detector

A presence detector comparison matters: PIR presence detectors trigger on body-against-background thermal contrast, and they fail in two well-documented scenarios — stationary occupants (sleeping, reading, desk work) and rooms where ambient temperature approaches body temperature in summer. This WiFi mmWave presence sensor outperforms PIR presence detectors in both cases. The wideband 24GHz radar core detects micro-motion and breathing at 2.5m, holding the room "occupied" while a guest sleeps — a presence detector behavior PIR presence sensors cannot match. The 10m motion range covers large hotel rooms and meeting spaces from a single ceiling presence sensor, while the 2.5m micro-motion range ensures a sleeping or seated guest is never missed — the presence sensor detects breathing, not just movement. Most mmWave presence sensors on the market detect micro-motion at only 1.5m or less; our presence sensor reaches 2.5m, covering the full bed area. PIR presence sensors suffer high false-positive rates in summer when ambient temperature approaches body temperature; this WiFi mmWave presence sensor is unaffected by ambient temperature. Standard 5.8GHz presence detectors lose accuracy against reflective surfaces; this wideband mmWave presence sensor is robust to indoor multipath.

No gateway, no friction

The WiFi presence sensor connects directly to 2.4GHz WiFi and the Tuya cloud, so this presence sensor works in buildings where deploying a Zigbee gateway network is not practical. The presence sensor is the fast path for retrofit hotel and serviced apartment projects that need presence detection without a separate hub. A WiFi presence sensor means no extra hardware — just pair the presence sensor with the Tuya app and the presence sensor is online.

Installation and power

The presence sensor flush-mounts into a standard ceiling cutout. DC5V low-voltage input simplifies OEM integration — the presence sensor is embeddable into powered fixtures, USB-powered installations, or battery-backed building systems. For retrofit projects, the presence sensor pairs with a supplied DC5V power adapter. The WiFi presence sensor is designed for fast installation where a presence sensor needs to be deployed without infrastructure changes.

Presence Detection Sensor for Smart Building Automation

A presence detection sensor sits at the heart of any modern smart building automation stack — HVAC zoning, lighting scenes, occupancy-driven energy savings, housekeeping scheduling. This presence detection sensor combines 24GHz wideband mmWave radar with WiFi so the presence detection signal is broadcast directly to the cloud for remote monitoring. As a presence detection sensor, it reports three distinct states (motion, micro-motion, breathing) so downstream automation can pick the right state for the right action — for example, dim the lights to 30% on micro-motion, but keep HVAC at comfort on breathing only. For teams retrofitting existing buildings with presence detection sensors, the WiFi-direct design eliminates the need for dedicated gateways and reduces deployment cost. The presence detection sensor integrates with the Tuya cloud, major PMS platforms (CloudBeds, Mews), and Apple Home / Google Home / Alexa via Tuya integration for specifier-grade hotel automation.

mmWave Sensors and Modules Market: Where This Presence Sensor Fits

The mmWave sensors and modules market is segmented by frequency band, certification tier, and integration model. Entry-level consumer mmWave presence sensors (5.8GHz, WiFi/Zigbee) sit at the low end — they detect motion but lose accuracy on stationary occupants and lack enterprise certifications. Industrial-grade 60GHz mmWave presence sensors (Texas Instruments IWR6843, Infineon BGT60, Vayyar) target OEM integrators with reference designs and engineering support, but they require external radios for ecosystem integration. This WiFi mmWave presence sensor occupies the mid-to-premium tier of the mmWave sensors and modules market: 24GHz wideband mmWave radar core for stationary-occupancy accuracy, WiFi + Tuya cloud certification for ecosystem interoperability, and finished-product pricing in the 1,000-lot band. For presence sensor buyers comparing the mmWave sensors and modules market by use case, this WiFi presence sensor is the right fit for retrofit hotel and serviced apartment projects where gateway infrastructure is not available. The presence sensor is also available as a module for OEM integrators building their own mmWave sensors and modules market products.

Applications

• Retrofit hotel rooms: the WiFi presence sensor works where adding a Zigbee gateway is not practical — the presence sensor connects directly to the cloud.
• Serviced apartments: the presence sensor enables cloud-based smart locks and presence scenes without a hub. The WiFi presence sensor detects departure and triggers automation.
• Short-term rentals: the presence sensor provides automated check-out detection — the WiFi presence sensor knows when guests have left.
• Elder care: the presence sensor provides non-intrusive room occupancy with breathing detection — a WiFi presence sensor for healthcare monitoring.

Certifications and export

CE, FCC, and RoHS certified for direct import into EU and US markets — every presence sensor ships with compliance documents. ISO 9001 manufacturing ensures each WiFi presence sensor meets consistent quality. The presence sensor ships in 3-5 days for samples; mass production of the WiFi presence sensor runs 7-10 days with FOB Shenzhen, CIF, or DDP logistics. OEM branding and protocol customization are available at MOQ — your branded WiFi presence sensor, built to your presence sensor specification.
