AM2320 Temperature & Humidity Sensor: Wrong humidity value
Posted: Thu May 11, 2017 6:25 am
I have two different AM2320 temperature and humidity sensors. I am finding the temperature reading is about what it should be, but the humidity is out significantly. It is reading 39.3%, but it should be reading around 65%.
I am using the https://github.com/thakshak/AM2320/ library.
(note I left the issue report in Github about this)
Using a NodeMCU.
I have various other temperature and humidity sensors to obtain the 65% result from. These include AM2302 and BME280.
Unfortunately these sensors are not very popular, so not many people will find the same problem. Having said that I noticed many listings on AliExpress for the AM2320 state that it is replacement for the AM2302. Well it certainly isn't a drop in replacement, but I suppose any T/H sensor can be considered a replacement.
I saw one other person on another forum with a similar problem. Any suggestions regarding the humidity readings?
