USB vs Wi-Fi Data Loggers


USB Data Loggers

USB data loggers are electronic devices that monitor and store data, which can be quickly accessed by connecting to a computer. A USB data logger is known for its simple setup – just plug them in to retrieve readings. USB data loggers appeal to many customers because of their simplicity and affordability. Lascar provides pre-configured versions, which make installation even easier. USB data loggers are ideal for basic data logging tasks, providing a dependable and cost-effective method for monitoring and storing data.

Wi-Fi Data Loggers

Wi-Fi data loggers are flexible devices that wirelessly send information, reducing the need for manual retrieval. With limitless cloud storage, you can access your data from anywhere in the world, including a device on the opposite side of the world. Wi-Fi data loggers enable early detection of possible problems, through their real-time email and SMS alerts, potentially saving you the cost of lost stock. Wi-Fi loggers offer automated notifications and real-time monitoring, keeping you constantly informed of any changes. With these extensive features, Wi-Fi data loggers are perfect for continuous, long-term monitoring tasks, or for those applications where excursions in temperature or other environmental factors cause expensive losses.

When it comes to recording and accessing data, the EL-USB and EL-Wi-Fi have some interesting differences. With the EL-USB, you have to take the device out of service and plug it into a PC to access the data. Plus, alerts only come through the onboard lights and sounder (EL-SIE only), meaning you’ve got to be nearby to notice them. There’s also a limit of 32,000 readings stored on most devices.


In contrast, with an EL-Wi-Fi device, you can check your data in real-time through an app or online. Alerts are sent to you via SMS or email, and there are onboard warnings on the data logger too. The cherry on top is limitless data storage on the EasyLog Cloud, so you won’t have to worry about losing important information over time

The EasyLog Cloud platform provides a secure solution for storing and accessing your data remotely. It employs advanced encryption protocols and secure data transmission methods to ensure your information is protected.

Choosing the right data logger is dependent on your specific requirements. If you value cost, convenience of use, and secure data transfer, a USB data logger may be the best option. However, if remote access, real-time monitoring, and controlling many loggers from different locations are critical, a Wi-Fi data logger is the superior choice.

Imagine being able to monitor equipment performance in your manufacturing facility from your office computer or receiving instant warnings when humidity levels in your server room exceed acceptable limits – all without physically collecting the data logger. Wi-Fi data loggers offer unparalleled simplicity and a more comprehensive view of your monitoring environment, making them an excellent choice for applications requiring ongoing vigilance and remote access.

Consider your budget, desired level of data accessibility, and the scale of your monitoring project to make an informed decision.
