EL-USB-2-LCD+ for Data Logger for Vaccine Monitoring

Data Logger for Vaccine is not only important for human vaccines but veterinary vaccines as well. However, the environment for storing human vaccines and veterinary vaccines may be different. In this article, we will be exploring on how the EL-USB-2-LCD+ can help with the monitoring temperature and humidity and risk of potency of storage of livestock vaccines.

Livestock vaccines are a key asset to animals and people’s health. These vaccines are not only a cost-effective method to stop the spread of animal diseases, but it also helps to reduce and prevent transmission of zoonotic and foodborne infections to people. The usage of livestock vaccines would be an essential way to achieve maximal vaccine safety and efficacy.

Research carried out by the University of Bristol found that there are many guides on how to store vaccines that are intended for humans, but no clarity on storing vaccines for animals. Even though there are not many guides out there the recommended storing temperature for animal vaccines are between 2 to 8°C.

Thus, the primary intention of the study was to study the current refrigeration processes for storing of livestock vaccines. By studying the processes understanding the performance of on farm refrigerators and their ability to correct storage temperature would be a breeze. As the research team can evaluate the risks of storing livestock vaccines in fridges on the farm before animal application.

The Study

From January to August 2014, the research team have monitored the internal and external temperatures of 17 refrigerators amongst several farms. To conduct the research, the team used our Easylog EL-USB-2-LCD+ temperature and humidity data loggers. These temperature and humidity data loggers were then placed inside the chosen refrigerators, one at the top of the shelve and one at the bottom. Another logger was also placed outside of the refrigerator but in the same room as the fridge.

The temperature and humidity data loggers were configured to have a temperature reading of every 30 minutes which is recommended by the manufacturer Lascar Electronics. After the study was done, the results were compiled, and the temperatures were evaluated.

The Results

The recorded data from the loggers provided an enormous amount of raw information on the conditions inside the fridges. Ultimately, the results identified that all the fridges used across this study failed to sustain the correct temperatures needed to protect vaccine potency and therefore did not provide adequate conditions for vaccine storage.

The results suggested that on-farm vaccine storage is often neglected by farmers, and therefore suggested that vaccine storage on farms should be minimized. Alternatively, when vaccines must be kept on farms, then temperature monitoring of the refrigerator is highly recommended. Digital data loggers can be programmed to send automatic alerts via SMS or email to forewarn a potential temperature deviation, helping to minimize the risk of vaccines losing their potency and to ensure livestock vaccines remain efficient.

What are data loggers?

What are data loggers, you may ask? Never heard of data loggers and would like to find out more? Fret not, in this article we will be explaining to you what data loggers are and how they can benefit you for your personal use or for your business.

Data loggers are versatile tools used to collect and store data in a wide range of applications. From industrial settings to laboratory experiments, data loggers are designed to measure, record, and store data points over a given period of time. With the ability to capture a wide variety of data, they are essential to many industries and essential to the research process.

Data loggers can be used to monitor pressure, temperature, humidity, and other physical properties. These devices are also used in automation and control systems to monitor and adjust the environment to maintain a desired level of performance. In industrial settings, data loggers are often used to monitor and track production processes. This can help facilitate quality control and provide a way to track performance.

In the laboratory, data loggers are used to helping researchers analyze the results of experiments. Data loggers can be used to measure and record physical properties such as temperature, pressure, and humidity, as well as chemical properties such as pH, conductivity, and oxygen levels. By recording data over a given period of time, researchers can accurately track the performance of their experiments and identify areas for improvement.

Data loggers are also used in environmental studies to measure and record air quality, soil moisture, and others.

What can data loggers measure?

To begin with, data loggers are electronic devices that monitor the different types of conditions in an environment be it outdoors, indoors, or in extreme temperatures. Data loggers can record a wide range of applications ranging from temperature, temperature, humidity, carbon dioxide, voltage, current, light, and events.

The data loggers are then used to record and store data over an extended time period and you would be able to analyze the data that has been collected via software which can be easily accessed by plugging the data logger into your laptop or pc. You also have the option to send your collected data to our cloud software so that you would not lose any data recorded.

Now that we know what data loggers can do and measure, we will be moving on to what type of data logger we should use. USB or WiFi connectivity?

USB or WiFi Data Loggers?

The two most popular types of data loggers are USB data loggers and WiFi data loggers. Both data loggers have their own benefits, but it all comes down to your personal preference and which type of data logger would suit your application.

USB Data Loggers

The first type of data logger that we would be talking about is Lascar Electronics USB data loggers. USB data loggers are not only convenient due to its size, but it is also very easy to use. Depending on your criteria you may even get a USB data logger with an LCD display to view your readings immediately.

Some of our USB data loggers have very simple functions to the extent where some USB loggers can be activated by a push of a button. These USB loggers have a recording memory of a little over 30,000 readings to a whopping 1,000,000 readings. By now, you must be thinking to yourself with all that memory there must be a downside to it right? Well, not exactly. In fact, our USB data loggers are very durable and are able to withstand being rugged, weatherproof and are used widely in harsh environments such as farms and cold chain freezers due to their IP67 rating.

WiFi Data Loggers

Next would be the WiFi data loggers, these WiFi loggers are specially designed and manufactured to make it more convenient as your data or readings can be accessed via web software or mobile app. They can also be placed at a designated location permanently as you would view the readings via your mobile app. Not to mention you would not be missing out on any information either as you would receive email notifications for low battery, temperature or humidity breaches and disconnection of device. These data and recordings can also be downloaded via the cloud.

Lastly, most of our WiFi data loggers are also IP67 rated which means similarly to the USB data logger they can withstand rugged environment and conditions.

Where should I use my data logger?

As mentioned in the above, data loggers can be used for many different types of application. Our data loggers can be used to track the temperature of your personal fridge to monitoring the temperature and humidity of a cold chain process. Some examples of how data loggers can be used are as follows:

  • Temperature monitoring of vaccines in both storage and shipment
  • Temperature monitoring of food that is stored and transported is still safe to consume
  • Temperature and humidity monitoring of indoor and outdoor air quality
  • Temperature monitoring of food processes such as baking or pasteurizing
  • Automated temperature checks in medical and veterinary clinics
  • Humidity monitoring of buildings to keep it safe from mould and dampness

If these data loggers could bring benefit to you, look no further than our range of wireless and USB data loggers. Feel free to contact our sales team who will be happy to assist you in helping you find the right data logger for your use.

How does sensorist work

How does Sensorist work

One may ask how does Sensorist work? Well, before we begin. Have you had any trouble finding a solution to monitor the temperature and humidity of your fridge, industrial freezer, or any other temperature-sensitive items? Well, look no further as we introduce to you a simple yet effective and cost-friendly temperature and humidity monitoring system that will change the way LIVE temperature and humidity monitoring works.

So, one may ask what is Sensorist, what is so good about Sensorist and how does it work? In layman’s terms, Sensorist is a technology-changing temperature and humidity monitoring system that is applicable for a wide range of activities from simple monitoring of your very own wine cellar to a complex industrial building. Sensorist can do it all.

To begin, Sensorist works by having a gateway and a sensor. In each set or bundle, a plug to power the gateway, a LAN point, a Gateway, and a sensor is provided to kickstart your monitoring journey with Sensorist.
To set up Sensorist system first, the gateway has to be plugged into a socket to power it up. It also has to be connected to a LAN point as the gateway will act as the “brain” of the system. After the gateway is powered up we will then have to connect the sensor to the gateway via radio frequency or RF.

Now, you may think won’t radio frequency interferes with any of our electronics. The answer is no, using radiofrequency or RF as a connection will not affect any of your electronics even your walkie-talkie. Plus, connection with radiofrequency or RF is much stronger than using WiFi. In an open area, Sensorist’s Gateway and Sensor can be placed up to 900m apart and still be able to record.

Once everything is in working order, you can now begin to live monitoring your temperature and humidity. Since Sensorist has both a mobile app and computer software for you to configure your settings. You will receive notifications on both your mobile application and email if there is a breach of temperature or humidity. Mobile app and email notifications will also be activated if the battery of the sensor is low or a disconnection happens. However, fret not the sensor’s batteries would last around 2 years of use depending on the frequency of the reading.

So, how Sensorist system works on the Sensorist Cloud System is as follows. Once the sensor starts recording the environment’s temperature and humidity it then transmits its data to the gateway via radiofrequency. Once the gateway receives the data it then transmits the data to Sensorist’s cloud. Thus, you have the ability to recheck old data that has been recorded years back.
Users can also attach an external probe to monitor liquid temperatures or place the probe into a fridge or freezer to monitor the temperature while the sensor is still outside of the enclosed area. This would come in handy as a gateway can pair up to 99 sensors and all temperatures could be monitored via a mobile app or desktop website.

Case Study – Food distribution company
An example of Sensorist being used would be in a Food Distribution Company. Food Company A wants to have a monitoring system for 15 of its industrial freezers and chillers. As they realized that if they do not have a temperature monitoring system, accidents may occur without them knowing.

Such as a staff forgetting to close the door properly or if there is an electrical outage. This would be costly for them as their inventory would be damaged. In this case, Sensorist would be perfect for their application.

After a site visit, we noted that their chillers and freezers were located side by side to one another and all we needed was one gateway to connect all the sensors. Usually, the number of gateways varies from case to case as each company’s freezers and chillers are located at different locations. This also includes the availability of a LAN point and a socket to power the gateway.

To further make the system more effective probes were attached to the sensors and only the probes were placed into the freezer or chiller while the sensor is located outside. Even though, the temperature and humidity sensor itself is able to withstand temperatures up to -30 °C. It would be better to locate the sensor outside as we would be able to use fewer gateways, in which this case was only 1 gateway.

The reason for this is that the walls on the freezer and chillers are thick and once the sensor is placed inside, the connection level would be around 5-15% between the gateway and the sensor. Even though a connection level of anything above 5% is perfectly fine, sensors in the freezers or chillers that are located further away from the gateway may lose the connection because of this.

Once the sensors, gateway, and probes were in place Food Company A was able to start live monitoring and record the temperature of their freezers and chillers. The data would all be on one computer software that is easy to use and user-friendly. The data then can be viewed and printed via the software. The users are also able to set their temperature and humidity breach to receive alerts which is what Food Company A made their operations hassle-free and one less thing to worry about.

On that note, we will be ending our case study. If you have any questions regarding Sensorist’s temperature and humidity monitoring system or any of our products, feel free to contact us via email or contact form and we will get back to you as soon as possible.
