Hi,
After a period of being disconnected I activated my sensor again. But found incorrect readings:
PM10: 1999.90
PM2.5: 999.90
Is my sensor defective/end of life?
Welcome !
It could be a bit shifting in the serial.
Please check the connections and put a bit of contact fluid to remove oxidation.
Hi, sorry for the late answer. ll connections are soldered, so the connections should be ok.
Ok tested it all. No success. Ordered and installed new sds011. All working now. Thanks for the advices.
