CO2 Monitor Data Submission (Classroom Safety)

Jump Directly to Data Submission Form
Hello, and thank you for your assistance with this important project!  If you arrived at this page directly, please refer to our CO2 Monitors page first.

This page provides the data capture of low-end CO2 monitor against high-end (NDIR) CO2 monitor.  The purpose is to save teachers and parents from having to pay over $200 for a high-end version.  These individuals need a highly reliable, highly accurate solution without the bells and whistles.

Method

The CO2 data will be crowdsourced to get the widest variety of products, scenarios, and any product age-related concerns.

1. To participate, you need a high-end product with an NDIR CO2 sensor.  This can be an Aranet4, Temtop M2000C, or equivalent.
2. You will also need a low-end product that would likely be purchased by a teacher or parent.

3. Place the high-end and low-end product together.
4. Allow at least 90 seconds to pass for any disturbances (due to this movement) to reach equilibrium.

5. Capture the RH (Relative Humidity), temperature, and CO2 ppm for both sensors.  (If the low-end product does not have RH or temperature, this is fine to exclude this piece.)
6. Repeat these measurements in as many scenarios as it is convenient.  This can include in empty rooms, occupied rooms, and outdoors.

7. If the products are sampling at different rates, please only send data points where they have updated within seconds of each other.

If you have multiple units, please identify the model in the form below.  Otherwise, just provide an "X" if you have already submitted data.  Similarly, you only need to provide extended model data once.

Results

The form below will be active for several weeks.  As data is captured, it will be published.  If you leave identifiable contact information, you will be contacted to ask about if and how you would like your contribution to be attributed to you.

It is hoped that a low-cost model may be recommended to all teachers from your efforts.  If all models less than $100 are insufficient, Shift Sight will build one and offer it at-cost.

Thank you for your assistance in keeping children, teachers, and families safe!  Contact us if you have any questions.

We have some data but not enough to draw any conclusions or post meaningful results.  (We have background noise at this point.)

    CO2 Monitor Data Submission

    This identifies your particular unit. It is hoped that several individuals have the same low-cost unit so as to compare repeatability by manufacturer.
    If you have only one unit to compare against an Aranet4 (or NDIR equivalent), you only need to fill this out for your first data point. Leave an "X" if you are submitting subsequent data.
    If this is a model's first data point, you may also submit other relevant info such as age of unit and any extremes (high RH or high temperature) it was exposed to during your ownership.
    Please submit both a reading from the unit you are comparing and the Aranet4 (or NDIR equivalent) as a baseline. Also describe indoors, outdoors, crowded, empty, etc. Multiple points are fine and preferred. Separate them by rows.
    Max file size: 20MB
    If your data is stored as a file, you can upload it here. Simply add a comment to the "DATA POINTS" box such as "see file."

Shift Sight believes in leaving the planet better than we found it.  Your children deserve no less.
