Model C: Connected CO2 sensor with integrated battery and storage

Measures CO2 levels as well as temperature and humidity. Measurements are sent to the cloud at configurable intervals (when Wi-Fi is available and configured) so that you examine and analyze the data.

Without Wi-Fi or when Wi-Fi is deactivated, the sensor records the measurements in its internal memory so that they be uploaded to the cloud portal when Wi-Fi is available again or activated.

Free access to the cloud portal.

Features

• CO2 via dual-beam NDIR (Sensirion SCD-30)
• Records CO2 level, temperature, and humidity
• E-ink screen
• Wi-Fi connectivity (2.4GHz only at this time)
• Over 39 hours of battery operation (with Wi-Fi disabled)
• Configurable CO2 level alert threshold with alerts via e-mail and/or audible sound
• Screen refresh period and sample interval configurable via the cloud portal
• 48 months of data retention on the cloud portal
• Ability to update the firmware when available
• Charging via USB-C port (CAN/US, EU or AUS/NZ available as options)
• Optional desk stand and/or wall mount
