How to use?
How the thermometer and hygrometer work.
The thermometer is measured in degrees Celsius or Fahrenheit, while the humidity meter measures the relative humidity of the air at% RH. By adjusting the temperature and humidity inside the room, you can feel more comfortable (thermometers and hygrometers have been calibrated at the factory and the user has no need to make adjustments).
How the barometer works
Barometer hPa, kPa, mmHg, mb or inch and other units measured atmospheric pressure. The atmospheric pressure corresponds to the weight of the surrounding gas and is subject to weather conditions and local altitude. Observing the change in air pressure allows you to predict the weather. Please note the changes in the barometric pressure indicated by the pointer and observe the changes in the weather.
Elevated air pressure Sunny weather.
The pressure hangions Short sunny.
Lower air pressure The weather is bad.
The pressure drops exactly Thunderstorms.
Pressure fluctuates slightly The weather lasts.
