Sensitive elements

Temperature and humidity sensor

CO₂ (carbon dioxide) sensor

Temperature measurement

Sensitive element

Digital temperature and humidity sensor

Values in the Ajax apps are updated depending on the frequency of the "hub—detector" polling interval, but not less than once per minute.

Measurement range

from 32°F to 122°F

The value is available in the device States in the Ajax app.

Measurement accuracy

±0.36°F

Measurement pitch

0.18°F

The minimum temperature change value recorded in the Ajax apps.

Comfort level from 57 to 70°F

Temperature range

Humidity measurement

Sensitive element

Digital temperature and humidity sensor

Values in the Ajax apps are updated depending on the frequency of the "hub—detector" polling interval, but not less than once per minute.

Measurement range

from 0% to 100%

The value is available in the device States in the Ajax app.

Measurement accuracy

±1.8%

Measurement pitch

The minimum humidity change value recorded in the Ajax app.

Comfort level from 30 to 60%

Humidity range

Carbon dioxide (CO₂) concentration measurement

Sensitive element

digital carbon dioxide sensor

Values in the Ajax apps are updated depending on the frequency of the "hub—detector" polling interval, but not less than once per minute.

Measurement range

from 400 to 10,000 ppm

The value is available in the device States in the Ajax app.

Air quality assessment levels

normal air: up to 1000 ppm
moderately polluted air: from 1000 to 1400 ppm
polluted air: from 1400 to 2000 ppm
critically polluted air: more than 2000 ppm

Effects on well-being:
from 1000 to 2500 ppm— lethargy;
from 2500 to 5000 ppm—possible adverse health effects;
5000 ppm and above—the maximum permissible concentration during an 8-hour working day.

Measurement accuracy

±30 ppm or ±3%

When the CO₂ concentration is less than 5,000 ppm. For higher concentrations, the measurement error increases.

Measurement pitch

1 ppm

The minimum value of the change in carbon dioxide concentration recorded in the Ajax app.

Acceptable level to 1100 ppm

CO₂ range

Additional features

Charts

of temperature, humidity, and carbon dioxide concentration

Available in the Ajax apps. The data is updated in real time. Measurements are stored for up to 2 years.
Discrete value: 1 minute.

LED indication

green: Normal air
yellow: Slightly polluted air
red: Polluted air
purple: Сritically polluted air

The LED indicator on the device enclosure lights up in the event of a critical change in air quality. The user can also turn on the indication by touching the touch sensitive button on the front panel of the detector.

Automatic calibration

once every 1–14 days

The detector selects a calibration interval depending on the circumstances and automatically calibrates the carbon dioxide sensor. In normal conditions (ventilated room), manual calibration is not required. The digital humidity and temperature sensor does not require additional calibration.

Manual calibration

is run in the Ajax apps. Suitable for unventilated rooms. We recommend calibrating the detector once every 2-3 weeks in such rooms.

Scenarios

reactions to changes in temperature, humidity, and carbon dioxide concentration

For example, turning on plenum ventilation if the air quality deteriorates.

Backup memory

up to 3 days

If the detector loses communication with the hub (or radio signal range extender), it stores all measured values. After the connection is restored, all values are sent to the Ajax app.

Recommendations

The device is designed only for indoor installation at any height. It is not necessary to use the SmartBracket mounting panel.
The detector can be placed on a table or shelf.

Sabotage protection

Accelerometer

Notifies on attempts to tear off the detector from a surface, remove it from the mounting panel, or move the detector if it is placed on a table or shelf.
