Indoor air quality (IAQ). CO2 storage facilities leakage control. Smart ventilation systems. Restaurants and breweries CO2 level monitoring.

CO2 measurements:
Range: 400 to 5000 ppm
Accuracy: ± (40 ppm + 5 %)
Resolution: 1 ppm
Calibration: Automatic, if the sensor is exposed to fresh air for more than 30 minutes.

Pressure measurements:
Range: 10 to 1200 hPa
Accuracy (min): ±1.5 (25°C, 750 hPa)
Accuracy (max): ±2.5 (-20°C to + 85°C, 300 to 1100 hPa)
Resolution: 1 hPa

Humidity measurements:
Accuracy (min): ±3.0 %RH (in 20 to 80 %RH range)
Accuracy (max): ±5.0 %RH (in 5 to 95 %RH range)
Resolution: 0.1 %RH

Recommended operating range is 20% to 80% RH (non-condensing) over –10 °C to 60 °C
Prolonged operation beyond these ranges may result in a shift of sensor reading, with slow recovery time.

Temperature measurements:
Accuracy (min): ±0.4 °C (in -10 to +60°C range)
Accuracy (max): ±0.6 °C (in -20 to +60°C range)
Resolution: 0.1 °C
