Widely used in many industries today; the Data Logger has become a must-have device for today’s world. This device saves time and money in the long run, also; does the job more accurately and efficiently than us, the humans. We write this article for those who know nothing about this versatile data measuring and monitoring device. We cover many topics in this article; enjoy!
What is a Data Logger?
Well, this is an often-asked question from the experts in the industrial world. At a glance, this device is a measuring device. Anyway, it does more than just measuring, which makes it so special. In simple words, it measures environmental data by its sensors and saves the data in its internal memory. So, it does two jobs at once without any support from external parties (humans.) Well, many environmental data measuring devices are there such as the thermometer, humidity meter, and so on. None of these measuring devices can save the data for you. Hence, you can’t use ordinary measuring devices for environmental data monitoring process. Yes, before the era of the Data Logger; people were using ordinary measuring devices and recorded the data manually with a pen and paper. Let’s discuss the downsides of manual data recording methods in the next few paragraphs.
Modern manufacturers have managed to introduce compact versions of the Data Logger that looks just like an ordinary measuring device. You can easily carry it wherever and whenever you want. The automatic data measuring and storing process is the top advantage of logging devices. So, you can set the sample rate that you require and deploy the logger, and it does the job itself, automatically. A Data Logger that has a longer battery life can continuously monitor environmental data for weeks.
OK, we can explain the process to you with an example. Let’s say you want to measure the climate condition or the temperature changes inside an ice cave. You got two options here: 1) You can stay in the cave with a pen, paper, humidity meter, and a thermometer for a week, suffering from extreme cold and fear. 2) You can simply set a temperature/humidity Data Logger in the cave and relax at your home. The second option will save your time, money, and life, also; the end result will be more practical, efficient, and accurate. You don’t need to freeze yourself in the ice cave thanks to data logging devices that are available at affordable prices today. In other words, logging devices have made environmental data monitoring process a piece of cake.
How does a Data Logger work?
As mentioned, this device comes with internal/external sensors to measure environmental parameters such as temperature, pressure, wind speed, and so on. The data collected by the sensors then get stored in the internal memory chips or devices. The whole process happens automatically. The stored data can be retrieved by connecting to a laptop, PC, or a mobile device. Well, several methods are there to connect the Data Logger to the external device, and we will discuss the ways in the next few paragraphs.
What parameters can you monitor by logging devices?
You can use these versatile environmental data monitoring devices for hundreds of applications. Please follow this link to get a better understanding of what parameters you can monitor with data logging devices (https://en.wikipedia.org/wiki/Data_logger#Applications.) Due to unique properties such as the versatility and accuracy, logging devices are widely being in many industries such as the food, manufacturing, and beverage.
Retrieving data from your Data Logger
Old-days logging devices were able to monitor environmental data automatically as the modern ones. Anyway, modern manufacturers have modified this versatile device to meet the requirements of the fast-moving world. Wireless connection, USB-interfaced, cloud data transfer, Bluetooth, and GPS data transfer are the modern ways of data retrieving from logging devices today. So, you can monitor the temperature fluctuation inside your commercial freezer from anywhere in the world today. Just log in to your cloud account is all you have to do here.
Well, available features may vary depending on the Data Logger type, price, manufacturer, and country. For example, wireless logging devices are expensive than ordinary logging devices. Still, investing money in a full-featured logging device will save your time and money in the long run. Most modern logging devices can monitor more than one environmental parameter. The temperature/humidity Data Logger is the best example we can give you here. Such logging devices reduce the need for several logging devices for a specific application such as monitoring the temperature and humidity changes in a museum (one stone, two birds.)
Data Logger operation
Well, operating a logging device is not rocket science. It is simple as setting the sample rate you prefer and deploying the device where you want. Well, the sample rate is the frequency that the Data Logger will take a measurement of the environmental parameter. For example, you can set your logging device to measure the temperature in your commercial freezer for every five minutes or every hour. Anyway, remember that higher the sample rate, sooner the batteries will drain. To compensate such effects, modern manufacturers have introduced logging devices that with a longer battery life. Also, safety features such as saving data automatically in the internal memory in case of battery power failure. So, your critical data will be safe, no matter if the device’s battery dies unexpectedly.
How to choose the right Data Logger?
Make sure you buy your logging device from a reputable manufacturer/supplier in your city. Focus on the quality, not on the price of the device. As mentioned, buying a full-featured Data Logger is a better option for today’s world’s needs. If you are not sure of the right device type that suits your application the most; talk to your supplier or an engineer. Buying the wrong device type will not fulfil your requirements. For example, you will not benefit from having a temperature Data Logger if you have to monitor the wind speed in your area.
The sum of it all
Well, we hope that we have done a good job of making you understand what is a Data Logger! Contact us today if you have questions and concerns about this versatile environmental data monitoring device. The price of logging devices can range from $20-$5000. Well, if you look for a logging device for residential application such as monitoring room temperature/humidity fluctuations; buying a cheap Data Logger is more than enough.
