Tested overnight in the lab. This sensor has an extension cable soldered on. The RH was consistently 5-7% lower than the other 3 sensors (L1740398, T2130005, G4540023). I removed the extension cable, and the numbers were still low. I removed the humidity chip, and it read 150%. When I replaced the humidity chip, the RH was within 2-4% of the other 3 sensors. I added the same extension cable back on, and the numbers became low. This sensor doesn't look consistent and needs more testing before it can be deployed. |
