Nextriv Sense IAQ Comfortair quality sensor with PM2.5/PM10

What it is for

Some spaces need more than CO₂: lobbies with doors onto a busy street, airport terminals, shopping centres, zones near print shops and workshops. There, air health is decided by PM2.5 and PM10 particulates — particles fine enough to reach deep into the lungs, and invisible enough that without measurement nobody knows about them. Nextriv Sense IAQ Comfort takes everything the 7-in-1 variant can do and adds a professional-grade laser particulate sensor.

This is a device for high-traffic facilities where comfort is the product: a passenger, a mall customer or a hotel guest will never see the ventilation system, but they will feel its effect. Laser-scattering particulate measurement also makes it possible to objectively assess HVAC filtration performance — a filter "due for replacement" stops being a matter of schedule and becomes a matter of data.

Devices of this class prove themselves in the most demanding public spaces — from airport terminals to large-format shopping centres — where the data ties into building automation and steers ventilation in real time.

Beyond particulates, the device measures temperature, humidity, CO₂ (NDIR), volatile organic compounds, pressure, light and occupancy — eight parameters from a single mounting point, with a large e-ink display that communicates the air status to everyone passing by.

Particulates are measured across the full 0–1000 µg/m³ range — from "alpine air" to emergency conditions — with ±10 µg/m³ accuracy in the range that matters most for health. The laser sensor is the most power-hungry element of the device, so for dense particulate sampling we recommend USB-C power; for less frequent measurements replaceable batteries suffice. In zones with variable traffic it pays to pair the measurement with the occupancy sensor: dust levels rise with foot traffic, and the data shows that relationship in black and white.

Usage scenarios

• Airport terminals: sensors of this class deployed across departure and arrival halls continuously measure CO₂, temperature, humidity and volatile compounds. Staff react faster, and ventilation runs against the real occupancy of the halls.
• Shopping centre: sensors integrated with the building automation platform optimise the air for customers and tenants while cutting HVAC energy use.
• Office by a busy artery: PM2.5 measurement shows how much smog comes inside with every door opening — and whether the supply-air filters really stop it. The decision to upgrade the air-handling units with better filtration is made on a chart, not a hunch.
• Technical workshop and print shop: zones generating dust and fine aerosols get their own watch. The acoustic alarm is a reminder to crank up the extraction ventilation.
• Hotel with a wellness zone: one sensor watches stuffiness (CO₂), air dryness (RH) and dust (PM) at once — reception sees guest comfort in numbers before a review appears.
• Clinic waiting room: in smog season, PM measurement at the entrance helps decide the operating mode of the air-handling units and protect patients with respiratory conditions.

Key features

• Laser-scattering measurement of PM2.5 and PM10 — technology from professional air quality stations in a wall-sensor enclosure.
• 8 parameters from one mounting point — a complete set of data on the air and on space utilisation.
• Large 4.2″ e-ink display with emoticons and "traffic lights" — communicating with the occupants of the space without an app.
• Acoustic alarm on threshold breaches — a reaction on site, not only in the platform.
• Smart display sleep when the room is empty (motion sensor) — energy savings with no loss of data.
• 18,000 records of tamper-proof local history + retransmission after connectivity outages.
• Configuration with a tap of a smartphone (NFC); USB-C as a power and service port.
• Flexible power: replaceable batteries or USB-C — recommended for frequent particulate sampling.
• The same flat white enclosure as the rest of the series — a consistent look for the whole fleet on the walls.

In the Nextriv system

Eight metrics means eight independent threshold sets in the Nextriv platform — two warning and two critical each, with event deduplication and clear alarm codes. Notifications go out over six channels (e-mail, SMS, web push, Discord, MS Teams, in-app sound), and rules and escalation policies match the alarm flow to the facility's procedures — from reception to the technical department.

Dashboards with nearly 20 widget types put particulates side by side with CO₂ and zone occupancy; PDF reports document environmental quality for tenants and the board, while XLSX/CSV exports feed the customer's reporting systems. The platform flags a sensor as offline after just twice its reporting interval — no measurement point disappears quietly. Notification rules split events between teams — engineering gets particulates and HVAC, reception gets guest-zone comfort — while quiet hours protect against an alert avalanche at peak times. Measurement history reaches back up to 5 years: smog seasonality is plain to see, year over year.

Typical deployments

• Commercial buildings: lobbies, common areas and high-traffic terminals — comfort measured where thousands of people pass every day.
• Malls and retail: PM and CO₂ data integrated with HVAC automation — air for customers without burning energy.
• Hotels: guest comfort in numbers: stuffiness, dryness and dust under one watch.
• Schools and healthcare: a fuller picture of the air where vulnerable groups spend time — with alerts on particulate breaches.
