Red wine is very sensitive to light, so it should be stored away from light. The ideal storage temperature should be about 12℃-15 ℃. The wine should be kept in environment at about 70% RH. Therefore, They need to be stored in a special wine cellar. And our COEUX-WIFI temperature humidity sensor is needed to monitor the temperature and humidity in the environment.

Cigarettes also need to be stored in a certain temperature and humidity environment. This wireless temperature and humidity monitor can monitor the temperature and humidity for a long time to ensure that they are under the appropriate temperature and humidity.

The COEUX-WIFI room temperature humidity controller is mainly used for indoor temperature monitoring, such as in the baby room, living room, baby room and other rooms to display the temperature and humidity in real time. You can intuitively view the current temperature and humidity, Max. and Min. temperature and humidity values, date and time.
