The measurements are available on the integrated 2.7\" E-Ink display directly on site, supplemented by a trend bar showing the last 25 CO2 measurements and an icon for assessing air quality. A Senseair Sunrise NDIR sensor with pressure compensation is used as the CO2 sensor, and the power supply is provided by two replaceable ER18505 batteries with a combined capacity of 8000 mAh.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eMain features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003e2.7\" E-Ink display showing CO2, temperature, humidity, atmospheric pressure, CO2 trend, signal strength, and battery level\u003c\/li\u003e\n\n\u003cli\u003eLoRaWAN 1.0.3, Class A, OTAA, freely configurable transmission interval (default: 20 minutes)\u003c\/li\u003e\n\n\u003cli\u003eConfiguration via Bluetooth or LoRaWAN downlink, firmware updates via OTA\u003c\/li\u003e\n\n\u003cli\u003eCO2 and temperature alarms with adjustable thresholds, as well as data logging: If no network is available, the measurements are stored locally and transmitted later\u003c\/li\u003e\n\n\u003cli\u003eCO2 calibration via button press in fresh air, automatic baseline correction (ABC) can be enabled\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003eCO2: NDIR (Senseair Sunrise), 400 to 10,000 ppm, accuracy ±(50 ppm + 3% of the measured value), with pressure compensation\u003c\/li\u003e\n\n\u003cli\u003eTemperature: Sensirion SHT41, -40 to +125 °C, accuracy ±0.2 °C\u003c\/li\u003e\n\n\u003cli\u003eRelative humidity: Sensirion SHT41, 0 to 99.9% RH, accuracy ±1.8% RH\u003c\/li\u003e\n\n\u003cli\u003eAtmospheric pressure: 300 to 1100 hPa, accuracy ±0.3 hPa\u003c\/li\u003e\n\n\u003cli\u003eOperating conditions for CO2 measurement: 0 to 50 °C, 0 to 85% RH, non-condensing\u003c\/li\u003e\n\n\u003cli\u003eDisplay: 2.7\" E-Ink\u003c\/li\u003e\n\n\u003cli\u003eRadio: LoRaWAN 1.0.3 Class A, EU868, max. +22 dBm, sensitivity down to −139 dBm\u003c\/li\u003e\n\n\u003cli\u003eBattery: 2 x ER18505 Li-SOCl2 (4000 mAh each), non-rechargeable, replaceable\u003c\/li\u003e\n\n\u003cli\u003ePower consumption: 9 µA in sleep mode, 125 mA when transmitting at 20 dBm\u003c\/li\u003e\n\n\u003cli\u003eBattery life: according to Dragino, 2 to 8 years with a 20-minute transmission interval, depending on radio conditions.
