User Interface
Can the sensor display the CO2 level to occupants? If yes describe.
Yes - Display available through web, no account required
User Interface
Can the sensor display a visual indicator to occupants that the CO2 level has exceeded a programmed threshold? If yes, describe (what does the indicator look like, what the default thresholds are, and can the threshold be changed).
Yes - the web interface is completely customizable and accessible to occupants (no login required)
Reporting Capabilities
Can the sensor alert facilities (such as an email, text, or call phone application) when the CO2 level has exceeded a programmed threshold? If yes, describe (what does the indicator look like and can the threshold be changed).
Yes - The facilities dashboard can be used to configure alerts for elevated CO2 levels that are then sent by text or email
Reporting Capabilities, Integration Capabilities
How can the CO2 sensor data be logged? If proprietary software, describe (what type of account is needed, what logging intervals are available, what does it look like, and describe its capabilities including data download capabilities).
Wifi with proprietary software. Logging intervals are adjustable down to 1 second. Data can be downloaded to a CSV file or pdf. Data files can be configured to be e-mailed automatically.
Integration Capabilities
Can the CO2 sensor interface with a building automation system (BAS) or demand control ventilation (DCV) system controller? If yes, describe if integration capabilities are vendor specific.
Yes - Siemens Connect Ecosystem only
Integration Capabilities
