XCspec Air Quality Display Carbon Dioxide (C02) Sensor Image

XCspec Air Quality Display *Discontinued*

The AirWatch Display is a carbon dioxide, temperature, and humidity sensor that can be used for long-term monitoring and demand control ventilation.

Hub Highlights:

Three color LEDs indicate CO2 range. Display of CO2 value publicly accessible through mobile app
Easily connected to any building automation system for monitoring or ventilation control
Excellent performance on Hub CO2 accuracy testing protocols
Includes temperature and humidity sensors

User Interface

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

Yes - Display available on iOS and Android app, 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 - LED light turns orange when CO2 exceeds configurable "orange limit" (default: 800 ppm) and red when exceeds configurable "red limit" (default: 1100 ppm). 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 iOS and Android apps can be used to configure alerts for elevated CO2 levels that are then sent by 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. Data logging interval is 30 seconds. The phone app allows viewing limited historical data in a table. Max CO2 concentration for the past five occupied periods is available. A Wifi portal allows viewing of live data and downloading the data through to a CSV file. Sensor must be connected to the internet. XCSpec partners, EnerAllies and Environsense, also have a web portal that supports CO2 (and other parameters) logging and report generation.

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 - Through a 0-10V output or via the XC Spec DCV Pro controller

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

Yes - Requires logging into a local wifi portal to configure

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
