Wrong Data, or SDS011 and BME 280 broken

Hello everyone. For a week now, my sensor has been delivering incorrect data. Occasionally, the correct data is displayed. Does this mean my sensor is broken? The second sensor works fine, but the BME280 isn’t delivering any data. Is it also broken, or am I doing something wrong? Thanks in advance.


Hi,
Open the sensor désoxidize everything.

Hi, thanks for a quick reply. Would you tell me please how to do it? ( maybe link with tutorials) Cant find anything in internet. Dont want to brake a sensor. Regards

Unplug the dupont cables and brush gently the pins with a toothbrush with white vinegar or better Kontakt 60 anti oxidation fluid. Check the small Board of the bme if there is some white powder. And also on esp.

Thank you. So looks BME Sensor.

It is basically oxidized.

@pjg ,Thanks a lot !!! Works fine ( 2hours already) :smile: Have great day !
