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.
