I did get shipped the correct sensor, an MH-Z19B. It seemed to work just fine and matched what my calculations said it should be reading in my space, but after a while it only reads 0 ppm even though the orange indicator light is still blinking.Am I missing something? The documentation is unclear as to why it would work well for a month and then only read 0 ppm.I would welcome feedback from the supplier or an updated documentation. I’m not sure if the sensor is faulty or needs recalibrated.

This is a MH-Z19C, not a MH-Z19B

The title suggest that you will get the better MH-Z19B. Then further down the description it is mentioned that you might get either the MH-Z19B or the MH-Z19C.Should I be surprised about what I will eventually get? Yes of course I got the cheaper MH-Z19C.This seller is exploring the boundaries.
