Why choose a wall-mount presence sensor for retrofit projects

The Wall Mount mmWave Human Presence Sensor is a wall-mount presence sensor that brings true presence detection to a standard 86mm wall box. As a presence sensor, it gives specifiers what a basic presence sensor cannot: occupancy detection without ceiling modifications, deployed into any existing wall switch position. Where ceiling-mounted presence sensors need above-ceiling wiring, this wall presence sensor installs into any existing wall switch position — the fast retrofit path for offices and hotels that cannot cut into ceilings. The presence sensor is the ideal solution when a ceiling presence sensor is not practical. This wall presence sensor delivers the same mmWave detection as our ceiling presence sensor, but in a wall-mount form factor. For teams retrofitting existing buildings with presence sensors, this wall-mount presence sensor is the de-facto reference for building automation projects that require presence sensor deployment without ceiling infrastructure.

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 wall-mount 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 same wideband mmWave radar core as the ceiling presence sensors — 24GHz, 10m motion, 2.5m micro-motion, breathing detection, 120° field. This wall presence sensor uses front-facing radar that covers large meeting rooms or open-plan office zones from a single wall-mounted presence sensor. Most mmWave presence sensors on the market detect micro-motion at only 1.5m or less; our presence sensor reaches 2.5m, covering a workstation or meeting table from a single wall mount. Standard 5.8GHz presence detectors lose accuracy against reflective surfaces; this wideband mmWave presence sensor is robust to indoor multipath.

Detection performance

The same wideband mmWave radar core as the ceiling presence sensors — 24GHz, 10m motion, 2.5m micro-motion, breathing detection, 120° field. This wall presence sensor uses front-facing radar that covers large meeting rooms or open-plan office zones from a single wall-mounted presence sensor. Most mmWave presence sensors on the market detect micro-motion at only 1.5m or less; our presence sensor reaches 2.5m, covering a workstation or meeting table from a single wall mount. The 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. Where a ceiling presence sensor covers from above, this wall presence sensor covers from the side — the presence sensor for spaces without ceiling access.

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, meeting-room booking verification. This presence detection sensor combines 24GHz wideband mmWave radar with dual-mode connectivity (Zigbee + WiFi) so the presence detection signal integrates with any building automation stack. 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, mark a meeting room as "occupied" on micro-motion, but keep HVAC at comfort on breathing only. For teams retrofitting meeting rooms and open-plan offices with presence detection sensors, the wall-mount form factor and 86mm wall-box compatibility eliminate the need for ceiling work. The presence detection sensor integrates with Tuya Smart Life, Zigbee 3.0 gateways, Apple Home, Google Home, and Alexa for specifier-grade building 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 wall-mount 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, dual-mode Zigbee + WiFi 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 wall-mount presence sensor is the right fit for retrofit office and hotel projects where ceiling work is not possible. The presence sensor is also available as a module for OEM integrators building their own mmWave sensors and modules market products.

Dual-mode flexibility

This wall presence sensor supports both Zigbee and WiFi in one presence sensor. Commissioning teams can pick the radio that matches each project: Zigbee mesh for whole-floor scale where the presence sensor joins a mesh network, or WiFi direct for simple single-room retrofits where the presence sensor connects to the cloud. No need to stock two presence sensor SKUs — one wall presence sensor handles both protocols. The presence sensor switches protocol during commissioning, making this the most flexible wall presence sensor for mixed-protocol deployments.

Installation and power

The wall presence sensor fits a standard 86mm wall box (single gang). DC5V low-voltage input enables OEM integration of the presence sensor, and a supplied power adapter supports wall-box retrofit installations of the presence sensor. Custom faceplate colors are available at OEM MOQ for hotel brand consistency — your branded wall presence sensor with a faceplate that matches the room. The presence sensor installs in minutes without ceiling work, making it the fastest presence sensor retrofit path.

Applications

• Open-plan offices: the wall presence sensor provides presence for HVAC and lighting zones. The presence sensor covers up to 10m from the wall.
• Meeting rooms: the presence sensor provides booking system presence verification — the presence sensor prevents false "available" status when someone is inside.
• Hotels: the wall presence sensor handles bathroom and corridor presence automation without ceiling work. The presence sensor fits standard 86mm wall boxes.
• Residential: the presence sensor enables 86mm wall-box presence automation — a wall presence sensor for smart homes without ceiling modifications.

Certifications and export

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