    New CO2 Sensor Tech

    Read an interesting article on a potential new CO2 sensor technology.

    The real question is his fast the reaction happens so you can be alerted. The biggest problem today with CO2 sensors is that by the time they warn you of a problem you are in position that warning is usually too late

    Now if they could just do that for Oxygen

    Hm, based on what do you think so?
    CO2 sensors are fast enough for detection of levels of CO2 in CCR to alert soon enough for diver to take action and avoid CO2 hit.

    Hi Andrew-

    Excellent article. Thanks for pointing this out. Great potential here.

    While this is strictly at the embryonic stage, the key is that the "something" which this new transducer element measures to calculate CO2 is a DIFFERENT something than any other sensor to date.

    'Minor' details like sensitivity to moisture, durability, and actual total power use of a sensing system that turns that "something" into a number on a display- or an alarm- will make or break its future.

    I base it on real life experience. The CO2 sensor on the explorer (same as sentinel) on a breakthrough would register one reading below threshold and the next reading would be already be well beyond bailout and into the impairing range. I think it jump from 1-2mbar to 15-20.

    The problem is a breakthrough occurs quick and when it does CO2 elevates a rate that few seconds between samples could be too late.

    Hm, if I do not mistaken from breakthrought to hypercapnia is not fewe secconds, but a bit longer. And that time should sufice to bailout .... at least that was info I got from lot of users with CO2 sensors simulating breakthrought with leaving scrubber out of CCR. There was some time needed to rise the levels of CO2 high enough to provoke alert and than mild hypercapnia event (they bailout in time to prevent it)

    This is first time I hear for so fast jump from no C02 to so high levels.
