Temperature and Humidity Monitoring Protects Building Insulation

CAS DataLoggers recently provided the temperature and humidity monitoring solution for a large manufacturer of insulation materials. The company’s insulation material was absorbing a significant amount of moisture in storage and transit, so they wanted to conduct a ‘microclimate’ study of the best ways to pack their product and needed a portable temperature and humidity monitoring solution durable enough to withstand exposure to the weather.

Monitor and Alarm Food Storage With WiFi Capability

CAS DataLoggers is now offering the new EasyLog WiFi Temperature and Humidity Data Loggers to help protect perishable foods from spoiling in warehouses and inventories across the country this summer. A clear display lists temperature data from -20°C to +60°C (-4°F to +140°F) and instantly triggers alarms using audible alert and visual indications. Operation is quick and easy, and users can quickly access all the data using convenient USB connection. Read more on our Product Announcements page.

Temperature Monitoring Systems For Your Business Office

T&D’s Economical and Compact Data Logging Solutions

Office environmentWhen creating a productive office environment, it’s important to ensure that your employees are not too warm or cold, especially when your heating system is remotely-controlled which distributes heat unequally. When working in unpleasant conditions, people quickly become uncomfortable and start showing less energy–if the temperature is too warm, workers become tired, and when it’s too cold, their attention drifts and makes them easily distracted, so you’re advised to always keep the temperature between 67° to 73°F.

Temperature and Humidity Monitoring in Ice Wine Harvesting

CAS DataLoggers recently provided the temperature and humidity monitoring solution for a small winery in Ohio which was waiting for winter temperatures to drop low enough to harvest an acre of grapes to make ice wine. Earlier in the year, these grapes were left to freeze on the vine, where their water froze and their sugar became strongly concentrated. The resulting wine was exceptionally sweet and in high demand. However, the harvesting process was demanding and even risky: growers needed a freeze to start picking, and a delay would result in many fewer usable grapes lost to hail, rot, and animals.

Cocoa Fermentation Using Wireless Monitoring

Wireless Data Logger w/ Temperature & Humidity External Sensors
CHESTERLAND OH—January 4, 2012

CAS DataLoggers recently provided the datalogging solution for a cocoa manufacturer which needed to record temperature and humidity in cocoa fermentation boxes in the tropics. The beans had to be carefully fermented to bring out the best flavors and give chocolate its richness. After farmers gathered the cocoa pods and scooped the cocoa beans out, the cocoa beans were fermented inside wooden boxes or “sweatboxes” for a period of six days. A 220 lb. batch of beans along with their pulp was placed in these boxes, and given the amount of fermentation, the temperature would rise quickly, often climbing to 122°F (48°C). Throughout the process, the beans also needed to be rotated within the sweatboxes. However, if they were rotated too often, the beans would be too oxygenated, overheating and causing dark blotches. If the beans were rotated too infrequently, though, fermentation would be incomplete since beans in the center of the sweatbox got less oxygen than those on the sides. The entire process was extremely painstaking, but without closely-monitored fermentation, the cocoa beans would not result in high-quality chocolate. Therefore the manufacturer required a wireless monitoring solution which could communicate with office computers to ensure that the temperature and humidity inside the sweatboxes did not exceed specifications.

The cocoa manufacturer installed 4 T&D RTR-503 Wireless Temperature and Humidity Data Loggers, along with a T&D RTR-500 Wireless Data Logger USB Base Station, atop the wooden sweatboxes. The external sensor on each RTR-503 datalogger was placed inside each box and began measuring and recording the temperature and humidity levels while the cocoa beans fermented inside. Each wireless unit had a temperature measuring range of 0°C to 55°C (32°F to 131°F) and a humidity measuring range of 10% to 95% RH. The loggers measured in both Celcuis and Fahrenheit and were housed in water-resistant cases, with a clear LCD display and options for screw terminals or wall mounts.

The loggers’ wireless communication ranged up to 150 meters (500 feet), and their data could be collected remotely via USB, GSM technology, LAN and handheld data collectors. Current readings and recorded data from the sweatboxes were downloaded from the RTR-503 data loggers (Remote Units) via wireless communication with the Base Station, and then by connecting them to a PC with a USB cable, the data was easily downloaded to an office computer. By registering another RTR-500 as a Repeater, the wireless range could be expanded even further. Each logger had an 8,000 data set memory and a battery life of about 10 months that could be upgraded to last about 4 years. A Base Unit could download via wireless communication one RTR-503 Remote Unit at full logging capacity in about four minutes.

Additionally, by registering the RTR-500 as a Base Unit, it was possible to download recorded data and current readings from the remote units and send the data by e-mail or FTP to a designated address. The unit was also set up to monitor for warnings and send warning reports via e-mail. Moreover, by sending the recorded data to the online T&D WebStorage Service, the manufacturer carried out monitoring of all current readings and/or warnings as well as shared the data via a PC web browser.

The wireless base station also included software for automated download, real-time monitoring, and email alarm. By setting the Warning Monitoring Function to “ON”, if the set upper or lower limits were suddenly exceeded and that occurrence had been judged by the RTR-500 to qualify as a warning, a Warning Report Mail containing warning details was immediately sent to up to four specified addresses, providing total transparency to the temperature and humidity profiling process.

The cocoa manufacturer realized several benefits to the fermentation process after setting the wireless Temperature and Humidity Data Loggers and the wireless base station to monitor temperature and humidity levels inside the wooden sweatboxes. The T&D wireless system not only monitored the cocoa beans but also sent the data to an office PC and even sent email alarms when temperature or humidity went out of specification. The recorded data also aided in analysis to make improvements such as finding the optimal rotation time. These dataloggers enabled workers to micromanage the painstaking fermentation process, ensuring a superior chocolate with a taste that made all the work worthwhile.
