• Measuring range: CO₂ 400...5000 ppm, temperature -25...+70 °C, humidity 0...100 % RH, pressure 300...1250 hPa
• Communication: NB-IoT (LTE Cat NB2), CoAP protocol, transmission interval 1 min...7 days; Bluetooth Low Energy for configuration
• Memory: 100,000 measurements, measurement interval 1 min...30 days
• Power: replaceable 8500 mAh battery, battery life up to 8 years
• Housing: white ABS plastic, 32.5 × 60 × 125 mm, 145 g with battery
• Environment: IP30, operating temperature -25...+70 °C, 0...99 % RH non-condensing

Intended for air quality monitoring in offices, schools, kindergartens, laboratories and server rooms. The sensor is configured and activated with the Efento mobile app over Bluetooth; firmware and settings can be updated remotely.

Complies with CE (RED), FCC and RoHS. A calibration certificate from an ISO/IEC 17025 accredited laboratory is available on request.
