User Interface

Can the sensor display the CO2 level to occupants? If yes describe.

Yes - Display on the sensor

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 - LED light turns yellow when CO2 exceeds configurable "yellow limit" (default: 800 ppm), red when exceeds configurable "red limit" (default: 1000 ppm), and purple when exceeds configurable "purple limit" (default: 4000 ppm). LED light also changes color when particulate matter exceeds configurable thresholds. Otherwise LED light is green.

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 website has a feature to enable e-mail alerts for elevated CO2 levels. Alerts need to be configured for each individual sensor.

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. Data collection interval is fixed at 6 minutes Data can be downloaded to a CSV file.

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

Integration Capabilities

If sensor can interface with a BAS or DCV system controller, is additional hardware required?

Installation

Does the sensor require specialized software for installation? If yes, describe

Installation

Does the sensor require specialized training for installation? If yes, describe

Operation

Does the sensor require on-going maintenance? If yes, describe

Operation

Does the sensor require service contracts for ongoing data access? If yes, describe
