No pm10 and pm 2.5 detection

Hi everyone, I have a problem with the pm10 and pm 2.5 sensor, no value, what could it be?
my sensor at a year and a half old


Did you try pulling the plug off and putting it back on?

Yes, I unplugged it and kept it off for 10 minutes and also tried to restart several times but it only shows temperature, humidity and pressure but pm10 and pm2.5 no at this point I think it’s the faulty SDS011 sensor

yeah that’s one possiblity.
If you haven’t tried yet, do you have another usb cable and/or charger to make absolutely sure it’s not power related?

Yes, I thought about it tomorrow we will do more in-depth checks
