What do you know about the Data Logger? Well, experts in the industrial world know about this device from A to Z. This compact, yet useful device has changed the way we used to monitor critical parameters such as humidity and temperature. Most loggers just fit in your palm (so compact.) Anyway, inside a Data Logger; there are several parts that store and transfer the data to your laptop or the smartphone. OK, you are a first-time Data Logger buyer, and that is why you are reading this article now. What should you consider when buying it? Everything is covered in this article.

Data Logger

* Your Application

No matter what your application is (residential, commercial, or industrial;) understanding it correctly is the first this to consider when buying a Data Logger. This device can measure hundreds of parameters such as light, temperature, humidity, water level, wind speed, rainfall, and so on. Every Data Logger is optimized for either one or more parameters. So, buying a device that is optimized for humidity is not advisable for monitoring water level. Anyway, modern loggers can measure and monitor more than one parameter. Still, they can only measure parameters that have some kind of relationship to each other. For example, temperature and humidity. As you already know, humidity is a temperature-dependent parameter.

Where should you place the Data Logger? Some devices can only be used for indoor applications. So, for outdoor applications; you must buy a device that is designed to withstand sunlight and rainfall. Special devices are available for underwater applications. Can you use a general Data Logger for underwater applications? In summary, choosing the right Data Logger type that suits your application is the first thing to consider during the buying process.

* Accuracy of the device

Well, most loggers are accurate than general measuring devices such as thermometers and humidity meters. The accuracy of the measurement is critical in many industries such as food and water. For example, a point one Celsius error can lead to a disaster in the food industry as bacteria can grow when the temperature drops by a marginal value. So, buying a Data Logger that comes with a +/- 2 degrees error is not advisable for food-related applications. A quick tip: for more accurate results, buy a logger that is accurate up to 0.2 Celsius.

What should you do then? Well, the accuracy may vary depending on the Data Logger type, price, and the manufacturer. It is obvious that higher the accuracy, more the price will be. Manufacturers proudly mentioned about the accuracy of their products on their websites. Anyway, you don’t need an expensive device for general applications such as home use. Buying a Data Logger that comes with an error of +/- 2 degrees is more than enough for home use. Well, don’t get me wrong here. If you produce food as a home business; you need to buy a more accurate device. If you are a first-time buyer; you may not know much about accuracy and the sample rate. Talk to an experienced Data Logger supplier so.

* Features and software capabilities

Depending on the application, you should buy a device that comes with extra features to make the process more efficient. How would you like to receive the data from your Data Logger? The wireless option is available on many devices today. Well, time was there when you needed wires and cables to connect the logger to a laptop or a PC. Those days are long gone now. Wires and cables — I hate them. OK, the time of PCs and laptops also becoming obsolete now. Mobile devices have taken over the world in this 21st century. So, if you are a fan of mobile devices, don’t worry; you can connect your Data Logger to a mobile device via Bluetooth connection now.

When talking about data access options, the cloud data storage is a thing to highlight. This is the latest data access option that has been introduced by a limited number of manufacturers today. More and more manufacturers are now introducing cloud data access option for their products now. Your Data logger sends data to your cloud account, so you can monitor it from anywhere in the world. Software features include graphing, analyzing, and error highlighting.

* Durability

Your Data Logger should withstand external factors such as sunlight, rainfall, moisture, high/low temperature, and so on. So, durability is a thing to consider when buying your device. If not, the money you spend on it will just be a waste. Can you afford it? I don’t think so.

* The manufacturer

It is obvious that you should buy your Data Logger from a reputable manufacturer who has good customer reviews and ratings. The Internet has made the buying process easy for us now. It is just a matter of typing what you need in the search engine’s search box. Buying your device from a manufacturer who has ratings over 4 stars is advisable. Also, consider the warranty they give for their products (it should be a minimum of one year warranty.) What do their previous customers have said about the “after purchase service?”

* Battery life and internal memory

Most data loggers are battery-powered devices for ease of use. Depending on the sample rate, the battery power may vary. Anyway, your Data Logger only consumes a tiny amount of power to operate unattended. Higher the sample rate, sooner the device will run out of memory and battery power. So, make sure you buy a device with a higher internal memory for high-sample-rate applications. If not, the device will run out of memory before completing the task.

* The price

Well, I don’t like to discuss “price” when I talk about a product or a service. Anyway, many buyers consider it as a top priority. The price of your Data Logger may vary depending on the manufacturer, accuracy, sample rate, internal memory, robustness, the number of sensors, and the country/state. The higher the price, more the features will be.

Data Logger

Some final words

Now, you know all the factors to consider when shopping for a Data Logger. Our previous articles have explained the applications and uses of this device in detail. So, if you are a first-time buyer; you will benefit from reading our previous articles. Don’t hesitate to ask as much as questions from the manufacturer or the distributor.
