The Sensor ONE family
Air is invisible.Understanding it shouldn't be.
Sensor ONE turns a changing room into a calm, readable view—without making technology the loudest object in it. Choose the compact room essential, or step up to broader sensing and battery-powered freedom.
01More screen, less device
A signature edge, by necessity.
The warm-white polycarbonate shell is designed around the e-paper itself. Its characteristic left-side chin makes room for the display connection, while the other three borders stay exceptionally slim and precision vents keep air moving through the enclosure.

02Information without the glow
Designed for a glance.
Sensor ONE turns temperature, humidity, pressure, VOC, carbon dioxide, and particulate matter into a calm monochrome dashboard. The e-paper face reads like ink in ambient light instead of adding another luminous panel to the room.

03Expanded sensing
More chemistry. More context.
Sensor ONE PRO keeps the complete core air-quality view, then adds six gas channels, a larger four-grayscale display, expanded wireless hardware, and an internal battery for placement from room to road.

Choose your Sensor ONE
One clear family. Two levels of insight.
Both models turn the air around you into an immediate, glanceable picture. Choose the footprint and sensing depth that fit your space.
Expanded insight
Sensor ONE PRO
A larger, battery-backed model for broader gas sensing and richer integrations.
- Six additional gas channels
- Larger four-grayscale e-paper display
- Wi-Fi 6, Zigbee 3, and Thread hardware

Designed around the air sample
A reading begins with better airflow.
Heat-producing electronics are separated from the sensing area, while active airflow draws room air across the sensor array. The architecture is designed to reduce self-heating bias and keep each reading responsive to the space around it.
- 01Draw in room air
- 02Keep internal heat apart
- 03Make change readable
Questions, answered
A few thingsto know.
The essentials for choosing and connecting a Sensor ONE model.
Sensor ONE · Everyday use
Get to know your room.
Start with a room you use every day. A few familiar routines give the numbers useful context.
01Home office
Follow a working day.
Check carbon dioxide before a meeting and again afterward. Compare the pattern with occupancy and your usual ventilation routine.
02Kitchen and living room
Put a reading in context.
Cooking, cleaning, and open windows can change what a sensor sees. Look at the individual particle and VOC readings alongside the time of day.
03Placement
Give the sensor a steady spot.
Choose an open shelf or desk with space around the air inlets. Keep the location consistent when comparing readings from one day to the next.
