How to set the temperature and humidity alarm in Germany?

German temperature and humidity alarm needs to set the alarm threshold of temperature and humidity first, and the appropriate alarm threshold can be selected according to different occasions. For example, the alarm threshold of temperature and humidity in the warehouse can be set to 0-50 degrees, 30-90%; The alarm threshold of wine cellar temperature and humidity can be set to 0- 10 degree, 60-90%; The alarm threshold of temperature and humidity in the cold room can be set to -20-0 degrees, 60-90%; Wait a minute. After the setting is completed, the system will automatically detect the temperature and humidity according to the set alarm threshold. When the temperature and humidity exceed the set alarm threshold, the system will automatically send out an alarm signal.
