Application
Red wine demands careful storage, away from light, ideally between 12ºC-15ºC and around 70% RH. Ensuring these conditions requires a dedicated wine cellar monitored by our COEUS-WIFI sensor, maintaining optimal temperature and humidity.
Cigars, like wine, need specific temperature and humidity conditions. This wireless sensor continuously monitors these parameters, ensuring cigars are stored in perfect conditions for preservation.
The COEUS-WIFI controller is an essential tool for indoor climate monitoring. Whether it's the baby room, living room, or any other area, it provides real-time temperature and humidity data, displaying current, max, and min values, along with the date and time.
