Solutions to the common problems of products

• Why does the temperature and humidity of the product show deviations from the real

temperature and humidity?

The product is calibrated by precision reference when it is manufactured, but each product

has a slight diﬀerence in their electronic material used to determine temperature and

humidity. Even if the product is calibrated, the measured data can't be as accurate as

standard references, this error is going to be less than 5%.

• Why does the product shows diﬀerent outdoor indoor date when the transmitter and host

are put together?

Host and transmitter have a slight diﬀerence in their electronic material used to determine

temperature and humidity, and they are individually calibrated by precision reference when

they were manufactured, this error is also going to be less than 5%.

• Why does the Weather Station and outdoor sensor lose connection?

A. Radio signals Easily absorbed by metal objects and not easy to penetrate the wall,

therefore, the distance in actual use will be much shorter than 80 meters (theoretical

value ).

host and occupy a channel.
