overview
Wine collections are traditionally stored in cellars. But in an almost entirely basement Texas, Free State Mark Nelson, owner of Classic Wine Storage Services, oversees multiple warehouses at the Dallas/Fort Worth Metroplex. Professionals agree that good wines are stored between 55 and 56 Fahrenheit with a relative humidity (relative humidity) of 65%. If wine is stored at high temperatures for long periods of time, compounds of chlorine and bromine travel from the cork to the contents of the bottle, making the wine unpleasant or "blocked". Maintain 65% relative humidity to prevent an overly dry environment that can dry out wine corks, allow oxygen to enter the bottle, and damage or oxidize the contents. Excessive humidity can damage wine labels.
challenge
In order to protect the environmental conditions in its facilities, classic wine storage and service, look for an independent temperature and relative humidity monitoring system. I wanted to avoid paying recurring fees," Nelson said. "Since many third-party monitoring services charge monthly for data, I needed to find a wireless solution that I could deploy and run myself. "
Solution KIT-ZW-TRH (ZW-003, ZW-RCVR)
After evaluating multiple systems, a HOBO® Wireless Temperature Monitoring Test ZW-003 Temperature and Humidity Logger, a Massachusetts-based supplier of Onset data loggers and weather stations, was selected. Compact system with low cost, including three wireless temperature/humidity sensors ZW-003, ZW-RCVR data receiver, connected to PC via USB interface, and software that allows users to view and analyze data, configure alarm notifications, and manage wireless Sensor Networks. Nelson installed the kit's three data nodes, the ZW-003, in his smallest warehouse, a roughly 7,500-square-foot refrigerated space. Nodes positioned on high racks are wirelessly connected to other nodes in a daisy-chain arrangement up to a distance of 300 feet.
Temperature and humidity measurements are recorded every five minutes and sent wirelessly to the system's data receiver connected to Nelson's PC, accompanied by hoboware® software that displays a near real-time view of the environmental data in graphical form. Nelson configured the software to automatically offload the data to an Excel spreadsheet file on his computer from Microsoft. This file is constantly updated using the Dropbox cloud location, the file hosting service. This enables Nielsen to access its data terminal equipment anytime, anywhere from a variety of networks. Nelson also relies on pre-set email alerts that alert him to temperature readings that measure above 60°F or below 50°F. Eventually, Nelson plans to have a web developer write code to extract data every 15 minutes from an Excel file and Send updates directly to the company's website. With this in place, clients will have total access to near real-time data.
