Dropped AirGradient One, CO2 reading suddenly super high

[SteveA]

One of my AirGradient One’s got dropped on the floor from about 4ft high. It still works, but the CO2 reading has been super high ever since. 1600 where I’d expect around 500. I have a second AirGradient One to compare it to.

I’ve opened it up to check the components are seated properly, but I think the CO2 sensor is soldered on.

Can a jolt uncalibrate the sensor?

I’m going to do a CO2 calibration, and see what happens.

[SteveA]

I recalibrated, and all seems fine.

Yes the CO2 sensor is sensitive to vibrations but a recalibration like in this case usually fixes it.
