- Temperature measurement
- Sensitive elementDigital 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 rangefrom 32°F to 122°F, The value is available in the device States in the Ajax app.
- Measurement accuracy±0.36°F
- Measurement pitch0.18°F, The minimum temperature change value recorded in the Ajax apps.
- Humidity measurement
- Sensitive elementDigital 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 rangefrom 0% to 100%, The value is available in the device States in the Ajax app.
- Measurement accuracy±1.8%
- Measurement pitch1%, The minimum humidity change value recorded in the Ajax app.
- Carbon dioxide (CO₂) concentration measurement
- Sensitive elementdigital 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 rangefrom 400 to 10,000 ppm, The value is available in the device States in the Ajax app.
- Air quality assessment levelsnormal 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 pitch1 ppm, The minimum value of the change in carbon dioxide concentration recorded in the Ajax app.
- Additional features
- Chartsof 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 indicationgreen: 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 calibrationonce 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 calibrationis run in the Ajax apps. Suitable for unventilated rooms. We recommend calibrating the detector once every 2-3 weeks in such rooms.
- Scenariosreactions to changes in temperature, humidity, and carbon dioxide concentration, For example, turning on plenum ventilation if the air quality deteriorates., Learn more
- Backup memoryup 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.
- Sabotage protection
- AccelerometerNotifies 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.
- Protection against spoofingdevice authentication
- Communication loss detectionwithin 36 seconds, The detection time depends on the Jeweller or Jeweller/Fibra settings., Learn more
