I was curious about the levels of CO2 in my room so I went and bought a sensor for my bedroom. I was somewhat appalled when I woke up this morning with heavy eyelids to see the concentration at 1700 ppm.

Guess I have to leave my door open now.

    Presumably some percent fail the test but most pass. How do you know if you’ve got a dud?

    I have owned enough electronics to know the percentage of duds is higher than you’d hope 😅
