What is a Data Logger?

A data logger is an electronic device designed to monitor and record operational parameters throughout a particular period. Each data logger has an attached sensor responsible for detecting all the information and then there is a computer chip responsible for storing all the information. Once the information is stored in the chip, the data is then transferred to the computer where it is analyzed by experts. 

To sum it up, it is a compressed device that runs on battery and is fortified with sensors, ports, and microprocessors. This device is capable of deploying in a variety of environments.

How Does a Data Logger Work?

A data logger works seamlessly. As mentioned above, this compact electronic device is equipped with a microprocessor, internal memory storage, and a stellar sensor to collect the data. There are two ways to analyze the data; one is by connecting it to a computer and using installed software, and the other way is to use a local interface to connect this device wirelessly.

The very fact that data loggers work perfectly without computers makes them extremely easy to use. Plus, you can completely customize its settings per your needs. If you only want information regarding the temperature and not humidity, then you can easily set it as you please.

Perks of Getting a Data Logger

If you are a car enthusiast, you might already be aware of the benefits of a data logger. If not, let's examine the perks of the data logger to convince you to get one for your car. 

Data Collection

Manual collection of data is a hassle! For starters, there is always a chance of error. Secondly, you need an individual whose sole job is to record all the important information and numbers revolving around the environmental metrics.


You can easily place a device where it is difficult for a human hand to reach. So you can safely place this electronic, sensor-embedded device, somewhere unreachable. In this way, you will get all the important data you need without going through a lot of hassle.


As electronic OBD2 data loggers operate digitally, you don't have to worry about somebody forgetting to record the numbers. This device is capable of keeping digital logs and you can even go back to these numbers and make a decision regarding the health of your car.

How to Choose an OBD2 Data Logger

It is better to choose a data logger when you have some background information. So far, you know what a data logger actually is, how it works, and some of its perks. Now it is time to shed some light on some factors you must consider before choosing an OBD2 data logger. 


Keep the price range in mind; a data logger does not cost you thousands of bucks. You can get your hands on a decent data logger at a menial price. So choose a data logger that falls in your budget.


Invest in a data logger that keeps itself up to date. Make sure you can update it when the new version of that system is available. Otherwise, there is no use spending money on an outdated legacy system.


Another factor to consider is compatibility. Make sure that the data logger that you are purchasing runs perfectly well with your car. In addition to this, make sure it connects easily with your Bluetooth and Wi-Fi connection.
