Your building's buzzing. Still, it’s tough to know what's happening inside phone booths, huddle rooms, and those small meeting spaces where real work gets done. Studies say up to 60% of ghost meetings happen in spaces under 100 sq ft. These rooms create friction: booked slots sit empty. There are lines outside busy booths. Noise leaks into open areas because nobody knows what’s actually free. Occupancy sensors change that - fast. Use Macro sensors for building trends, Micro sensors for room-level truth. Problem solved in days.

The Small-Room Blind Spot: Why Macro + Micro Matter

Most occupancy tracking stops at the floor or zone. You get peak hours and average stay time but miss the small stuff. That tiny four-person huddle room? No clue if it’s overbooked or forgotten. Phone booths? Vanish from reports completely. When you don’t see what’s really happening:

• Ghost meetings take up space but go unused.
• Teams crowd the few rooms they see as available.
• People settle in hallways and noise spreads because they can’t spot open rooms.

Macro sensors show big-picture trends. They track traffic and dwell time in open areas. Micro sensors fill the room-by-room gaps. They live in each small room and show you what's happening at the doorway or inside. With both, you get total portfolio trends plus exact room-level data. No more guessing which booths need more seats. Notice friction points and fix them with data you trust.

Where Macro Wins

Macro sensors scan for Wi-Fi and Bluetooth signals across wide areas. They’re great for:

• Counting who enters each floor
• Measuring how long people stay
• Spotting daily peaks

You use that data to plan capacity. Start open hours around actual traffic. Staff up based on real numbers. Spot underused wings or packed lobbies - no more guesswork.

Macro works fast. One device covers a big zone - hundreds of square feet. Just a few sensors per floor and you get live data in minutes. Finance and real estate teams love the overview: which buildings hum with activity, which ones sit half-empty. Still, Macro can't tell you if the wellness room on the second floor is open right now or if your booked huddle room is actually in use. For that, you need Micro.

Where Micro Is Mandatory

Use Micro sensors for small, enclosed spaces - phone booths, one to four-person rooms, focus pods, and wellness areas. These rooms change over fast. Floor-wide sensors miss that five-minute call or quick meeting. Micro shows you:

• Exactly how many people are in the room right now
• Booked versus actual use
• Real ghost meeting rates

Place them at doors to spot lines when a booth stays busy past its booking. See which four-person spaces are mostly solo workers. Use that info to change room mix as needed. Add more booths or adjust booking rules based on real usage. Make every space count.

Macro vs. Micro Occupancy Sensors: Key Differences

Here’s the breakdown:

• Macro sensors: Cover 2000-3000 square feet each on average, sometimes more in specific spaces. Fewer devices per floor. Scan ambient signals. Easy to install - plug in and go. Privacy stays strong. Cost is 8-10x less than cameras. But you only get zone-level data, not what’s happening inside each room.
• Micro sensors: Watch a single room using mmWave radar. mmWave spots even a quiet person breathing. Each device covers about 400 sq ft at a wide angle. Install in seconds. No batteries, Wi-Fi, or ceiling mounts needed.

Your trade-off: Macro needs just a few sensors per floor. Micro needs one per room. Still, the reward is detailed, exact, room-level data. Together, Macro + Micro give you full-fleet heatmaps and complete room detection - on one platform.

Fast-Track Installation of Occupancy Sensors: The One-Week Fix

Micro sensors go in fast. No wiring, no IT hassles, no ceiling ladders. Plug them into the wall. Facilities teams can cover a whole suite of rooms in a day. You get early data in minutes. It takes just a few days to calibrate, but you’ll see live counts right away. Occuspace installs are up in 1–2 days with real-time analytics.

For a mid-size office, you’re up and running in a week:

• Identify 50-100 target rooms in a day or two
• Install sensors over 2-3 days
• Go live with dashboards and exports by Friday

That matters when you’ve got a lease renewal or need quick data for return-to-office plans. You see value on day one. Refine settings in the first week, but the core numbers - occupancy, dwell, ghost meetings - appear right away. Fast feedback means you can try changes, measure the result, and adjust in real time.

Privacy-First by Design

You protect privacy from the start. No cameras. mmWave radar and PIR detect movement and presence - without images or personal info. Occupancy sensors share group counts only. You see “two people in the room” or “booth occupied,” not personal details.

Our privacy-first model delivers over 95% accuracy and keeps everyone anonymous. Here’s how:

• Set retention rules. Keep detailed data briefly. Long-term, only hold the trends.
• Aggregate low counts so identities stay private.
• Show zone heatmaps, not individual paths.
• Share what you collect and why, up front.
• Limit raw feeds to the right team members only.

Short retention- 30-90 days for details - keeps trust strong. Aggregate reporting means you meet privacy standards in any workplace.

Key Occupancy Sensor Metrics

Reliable metrics drive smart decisions:

• Occupancy: People in a space minute by minute
• Utilization: Occupancy as a percent of room capacity
• Daily peak: Highest occupancy each day
• Average daily peak: Peak averages across days for trend spotting
• Time-in-target: How often rooms hit your ideal occupancy window
• Dwell: How long people stay in each space
• Booked vs. actual: Compare bookings with true use. Spots wasted? See your ghost meeting rate.
• Cost views: Energy per hour in use, and how cleaning hours link to real visitor counts

A high ghost meeting rate? That’s space you can reclaim. See where real use outpaces reservations. Adjust spaces and save energy, based on facts.

Integrations and Quality Checks

Make occupancy data visible and actionable:

• Wayfinding screens show live “busy vs free” maps. Colleagues check before hunting for space.
• Automated cleaning triggers start when visits hit a set point or a room empties. Teams clean on actual use - not just on a schedule. That's typically a 20-30% labor savings.
• HVAC and lights adjust based on presence. Empty room? Systems scale back. Activity pops? Everything ramps up.
• Smart building integrations rely on strong privacy. You get aggregate data, never individual tracking. APIs and exports feed metrics into your BI tools, IWMS platform, and dashboards.
• Merge sensor insights with bookings, badge data, and tickets. See the big picture on one screen.

Check data quality along the way:

• Match door entry and exit counts to stay accurate
• Update sensor thresholds to keep counts true
• Spot and fix dead zones quickly
• Label every chart clearly: "occupancy" or "utilization," with time frames shown

Transparent, detailed reporting gives the whole team confidence. Certified HPE Aruba support means you set up fast with Aruba access points as anchors.

Executive-Level Gains: Why It Matters

No-shows drop, so you open more rooms without adding space. Most teams see ROI in 6–12 months—less rent, fewer wasted hours, better productivity. Search times shrink. The workspace just works better. Fewer empty rooms mean you can close floors, hold off on new leases, and fit your team to the real demand. Smarter energy use follows real occupancy patterns. Occupancy-based controls can cut meeting room energy use by 22%, often paying for themselves in two years.

Avoided costs add up: skipped expansion, leaner operations, optimized layouts. Quick rollout matters when leadership wants data for top-level decisions. Macro + Micro coverage gives you KPIs and detailed insights - fast. You make confident calls: which floors to close, where to add capacity, and how to shape your future office.
