V-LOG PRO OR WIRELESS SENSORS FOR SCHOOL SCIENCE?

Published: Sep-2026 | Category: General

There is no single correct way to collect data in a science lesson. Sometimes students need a self-contained logger they can take outside, check at a glance and use with existing sensors. In other practicals, connecting an individual wireless sensor directly to a computer or tablet may be the quickest and simplest approach.

Data Harvest offers both options. The V-Log Pro Data Logger combines built-in sensing, support for wired SmartQ sensors and on-screen data logging in one compact device. Data Harvest Wireless Bluetooth Sensors provide a flexible cable-free route for practical work using individual sensors.

So, what is the difference, and which approach best suits your classroom?

What is the V-Log Pro?

The V-Log Pro combines the strengths of the original V-Log and V-Hub in an updated data logger designed for classroom and remote data collection.

Its large graphical display and redesigned menu allow students to set up investigations, view current readings and review stored data directly on the logger. This is useful when taking a computer or tablet to the experiment would be inconvenient, such as during fieldwork or long-term monitoring.

The V-Log Pro includes:

• four built-in sensors for light, sound, humidity and air pressure;
• three external inputs for wired SmartQ sensors;
• Bluetooth and USB-C connectivity;
• a graphical display for viewing readings and recorded data;
• EasyLog, Meters, Snapshot, Timing and Counting modes; and
• an internal battery for portable and remote data logging.

For schools that already own SmartQ sensors, the V-Log Pro is particularly valuable. Existing wired sensors can be connected to its three external inputs, while Bluetooth allows captured data to be transferred to compatible devices for further work in EasySense2.

When is the V-Log Pro a good choice?

The V-Log Pro works well when students need a versatile, self-contained data logger rather than a separate device for every measurement.

It is especially useful for:

• field studies where students need to view readings away from the classroom;
• remote or long-term investigations that require data to be stored for later analysis;
• practicals using more than one SmartQ sensor;
• schools wanting to continue using an existing collection of SmartQ sensors;
• quick investigations using the four built-in sensors; and
• group work where each team benefits from a dedicated logger.

Because students can see data on the logger itself, they can check that an experiment is working before returning to a computer for more detailed analysis.

What are Wireless Bluetooth Sensors?

Data Harvest Wireless Bluetooth Sensors combine the sensing and data-logging functions within each sensor. They can connect using Bluetooth or USB to a compatible computer, tablet or phone running EasySense2.

This makes them a convenient choice when a practical needs one particular measurement and students want to display the data immediately on a larger screen. With fewer cables across the bench, groups can move equipment more freely and get practical work under way quickly.

When are wireless sensors a good choice?

Wireless sensors are well suited to:

• fast classroom setups using a laptop, Chromebook or tablet;
• practicals where unrestricted movement is helpful;
• live demonstrations displayed to the whole class;
• group investigations in which each group measures a different variable; and
• departments building a flexible collection of individual sensing tools.

Students can watch graphs develop in real time, compare repeated runs and use EasySense2 tools to examine values, trends and differences in the data.

V-Log Pro and wireless sensors compared

Do you have to choose only one system?

No. The two approaches can complement each other within the same science department.

A school might use V-Log Pro data loggers for fieldwork, multi-sensor investigations and practicals involving its existing SmartQ equipment. Wireless sensors can then provide quick access to specialist measurements or support practical work where direct connection to a student device is preferable.

Both approaches work with EasySense2, giving students a consistent environment for displaying and analysing their results. This helps them concentrate on the science: identifying patterns, comparing evidence and deciding what the data means.

Choosing the right option for your school

Before deciding, consider the equipment and devices your department already has, the practicals you run most often and where students will collect their data.

• Choose V-Log Pro if you want on-device readings, remote logging, built-in sensors or continued use of wired SmartQ sensors.
• Choose wireless sensors if you want a flexible, cable-free setup that connects individual sensors directly to classroom devices.
• Use both if different subjects, year groups and practicals need a mixture of standalone and device-based data logging.

A flexible approach to practical science

The best data-logging system is the one that makes it easier for students to collect reliable evidence and understand what it shows. The V-Log Pro provides an adaptable bridge between existing SmartQ sensors and modern Bluetooth data capture, while wireless sensors offer a simple and flexible route into real-time measurement.
