Monitoring Flower Storage Temperature Remotely

Accsense Wireless Temperature Monitoring System

CHESTERLAND OH—September 27, 2011

CAS DataLoggers recently provided the remote temperature monitoring solution for a fresh flower supplier who needed to monitor three remote storage sheds for temperature. Like everyone in the floral supply business, she was always expected to deliver reliably, and a single failure to keep the fresh-cut flowers cool enough could mean a missed shipment and a major loss of reputation. After harvesting, the fresh flowers needed to be kept at temperatures close to freezing, yet could not be allowed to freeze or they would be visibly damaged. Her product was extremely temperature-sensitive, so when her inventory went out of specification, it not only ruined valuable product, but also disrupted the supply chain flow, causing further shipping delays. Continuous temperature recording could help significantly in preventing losses, but the sheds were constructed of metal and located far apart, so the customer had to note that metal did not absorb radio signals but instead reflected them. With this limitation in mind, the customer needed a cost-effective wireless monitoring system that could work within the metal buildings and send all the temperature data online for easy storage and analysis.

The customer installed four Accsense A1-13 Wireless Temperature Data Loggers in each of her three storage sheds, placing them in the packing rooms and in the main coolers. Each sensor pod monitored the shed using an ambient temperature sensor capable of detecting a wide temperature range of -40°C (-40°F) to +70°C (158°F). The A1-13 pods were specifically designed to connect to three RTD 100 Ohm sensor inputs, allowing an increase in the amount of sensors per pod and reducing the cost per measurement. This model also featured two digital inputs and could easily be connected to a wide range of digital sensors. The wireless data loggers were then activated up to their 90′ indoor ranges, operating on either battery or AC power. An Accsense B1-06 Wireless Data Logger Gateway with built-in 10/100BaseT Ethernet was then installed per each wireless group of pods in each of the three sheds to make the online data easily accessible. Diagnostic LEDs gave clear indication of power, wireless status, and more. Each wireless gateway could support up to 16 sensor pods and matched the pods’ 90’ indoor range (250’ outdoor).

The B1-06 gateway sent all of the data to either the Rackspace secure servers or as a local ASCII stream, either of which the supplier could incorporate into her own custom software, including LabView. For example, the supplier’s custom-made Accsense graphs showed her a high-temperature alarm period. The secure servers could also send out voice, text or email alerts (with premium subscription) to inform the supplier and authorized staff when a temperature reading fell out of range. Additionally, data sent online could be downloaded as a CSV file and loaded into most database applications.

Due to the metal sheds, wireless signal transmission among them posed a potential problem, which was addressed building-by-building; the signals often simply reflected until they escaped the shed through a door seal or other discontinuity in the metal. However, the ability of the Accsense monitoring system to “mesh,” where all the dataloggers also acted as repeaters, greatly improved signal reception and transmission. To deal with the long distance from one building to the next, a directional antenna was connected directly to the B1 gateway. These commonly available antennas, used in pairs, greatly increased the range of the wireless signals, easily achieving distances of over half a mile.

The floral supplier realized several advantages from installing the Accsense wireless temperature system in her fresh-cut flower storage sheds. Her new wireless system was cost- and time-effective compared to manually recording the temperature, since automated monitoring was far less expensive and much more reliable while also being documented for future reference. The supplier could also set the system’s warning limits for a narrower temperature range if required. A typical setting for the customer’s cut flowers was every 10 minutes, with the trigger filter set to require 3 data points in a consecutive order to be out of preset limits before the alarm was triggered. If desired, the alarms generated by the system could be sent to customized phone or email lists. The Accsense system’s many programmable features also increased overall versatility in alarm settings. For example, the wireless system could check for alarms at different intervals than those used to record the data.

Remote Monitoring of Medical Incubators for Temperature and CO2 Level

Accsense Remote Monitoring System

CHESTERLAND OH—August 29, 2011

CAS DataLoggers recently provided the data logging solution for a hospital storing valuable life science samples in medical incubators. These incubators needed to hold samples under precisely controlled conditions for long periods of time–if a problem occurred while the samples were under incubation, the samples would be lost along with the time the materials were being incubated. The hospital’s incubators were typically operated at a constant 37oC (99oF) and a 5% CO2 level. Often, regulators required recording of incubator conditions since any deviations from these levels could cause serious problems. Therefore the hospital needed a remote datalogging solution to monitor its incubators and alert personnel if conditions inside the incubator suddenly went out of range.

The hospital installed an Accsense A1-01a Wireless Environmental Data Logger on top of its incubators, connected to an Accsense B1-06 Wireless Data Logger Gateway supporting up to 16 A1-01a sensor pods. A single A1-01a pod monitored temperature and CO2 levels for two incubators, providing simple and reliable online monitoring. The data logger ranges extended up to 250’ outdoors, 90’ indoors without obstructions, and could also act as a repeater for other logger signals, running on battery or AC power.

Three different monitoring methods could be used with incubators, including direct monitoring independent of the incubator itself. Monitoring the analog outputs of the incubator by using the incubator sensors could also be performed, as well as monitoring of the alarm state of the incubator via the incubator sensors. In the first case, independent temperature and CO2 sensors would have to be installed within the incubator work space. In the second and third cases, the incubator would have to be equipped with the appropriate outputs (often an option card from the incubator manufacturer) and a cable from the incubator to the sensor pod would have to be used. The hospital’s incubators were monitored using the first method described above using direct sensors, which were ordered alphabetically; changing their names allowed a consistent order to the readings.

Designed for general environmental measurements, the wireless A1-01a datalogger pods featured internal temperature, humidity, light and vibration sensors measuring every incubation parameter, as well as external 4-20mA and 0-5V inputs and 2 digital inputs. Screw terminal connectors allowed connection to a wide range of external analog sensors, and the data loggers also included a +5Vdc output to power external sensors. In the event the gateway couldn’t be reached, individual pods stored up to 255 data points until a connection was restored. The B1-06 wireless gateway formed the connection between the hospital’s data and the internet, featuring built-in 10/100BaseT Ethernet and supported DHCP and static IP addressing as well as SSL Encryption for secure communication. Diagnostic LEDs provided clear status indication while the gateway’s 1900-point sample data buffer further ensured constant and effective monitoring.

Additionally, the Accsense wireless temperature monitoring and alarming system provided the hospital with cloud-based data storage and reporting for hassle-free monitoring. Once connected to the B1-06 Wireless Gateway, the pods monitored and logged data with the ability to view and remotely access data in real-time. The B1-06 Wireless Gateway could send all the data to the secure Rackspace cloud server or as a local ASCII stream, which staff could incorporate into their own custom software including LabView. Data online could easily be downloaded as a CSV file and loaded into most database applications. Hospital staff downloaded measurement data for offline analysis, signed in to access reports and graphs, and could modify the system configuration from anywhere an internet connection was available. Sophisticated alarms monitored incoming data and could send email, pager or phone warnings to multiple designees whenever an alarm went off. The sensor filters were powerful enough that when the CO2 content dropped to near-zero during a loading operation, the alarm was not triggered due to correct filter settings. An Accsense online account gave instant access to charts showing all measurement history with ranges as narrow as 5 minutes or as wide as 90 days, and also offered a customizable interface featuring a dashboard showing the most recent measurements from all sensor pods.

The hospital benefited immediately from installing the Accsense wireless monitoring system in its medical incubators. The data loggers were used as a convenient temperature alarm system with email, pager or phone alert capabilities. Using the wireless data loggers made it possible to check the incubators before the samples had been destroyed, saving the cost of the time running the test and saving the samples in the incubator. The remote monitoring system saved significant time and money while increasing confidence in all the incubation test results. Once the readings were taken, a monitor was used to display CO2 level data by percentage for an incubator, as well as link quality, supply voltage, temperature, ambient temperature, and probe temperature. Multiple incubators were monitored from a single screen, along with freezers, refrigerators and cryogenic freezers. Further, the Accsense system’s cloud capabilities put the hospital’s incubation data online to offer management easy data accessibility and analysis. This, combined with the data loggers’ high accuracy, made for an effective continual monitoring solution. Check out the Accsense product overview page here.
