The sensor works as expected without any problems. The sensor values are very accurate, I tested this with 4 other different AQ sensors (WeatherDuino AQM2/3, a Tuya device and a DIY device). You can rely 100% on the Ecowitt WH45. I supply it with electricity via a solar cell (with a battery), the consumption seems to be very low, the coming season with less sun will show more details. The only thing I don't like is the look. As a purely indoor device, in my opinion the sensor should be a bit more inconspicuous, subtle and less noticeable.
Funktioniert TipTop und macht das was er soll!
Just add battery, and connect to USB socket and it flow.
For temp and humidity, readings seems accurate compared to other sensors.
For PM and CO2, I cannot certify as I do not have reference.
