EasySense VISION Wi-Fi   Home / Secondary Science Data Logging  

All the features of the 2011 BETT Award Winning Vision + Wireless network connection to multiple devices. A true collaborative learning experience with our FREE multiplatform EasySense Software.

With an iPad, PC, Android or Chromebook

Collaborative Learning: Student groups work together to plan and capture experiment data. Throughout the capture, each student receives live data on their own iPad. Post experiment, working independently, students can save, analyse, reach conclusions and write reports.

The EasySense iPad software is available free of charge from the Apple App Store

  • Realtime recording
  • Group collaboration (multiple iPads)
  • Multiple sensors
  • Overlay mode (repeat experiments)
  • Fast recording (50,000 per second)
  • 14 days remote recording (using VISION stand alone mode)
  • Store data on the iPad and in the cloud
  • eMail data to other devices
  • Compatible with PC EasySense software (free)
  • Analysis tools

Standalone - without a PC!
VISION offers many new and exciting features including a full colour high resolution LCD touch screen. The graphing and analysis tools, normally only found on the PC are now built-in. VISION can even print out the graph (to most HP PCL Printer) VISION is truly a stand-alone data logger and analysis tool.
VISION has a large user memory for storing data files. Captured data can be transferred to a PC either by direct USB connection, or via a Pen Drive (Flash memory stick).
Tip. At the end of a lesson students can save their data to a pen drive and transfer it back to a school PC or take it home to analyse and write reports on their own PC.

With a Projector

Simply plug VISION into a Projector (or monitor) and it automatically switches from the built-in LCD to the connected display.

  • This is absolutely essential in a classroom setting, required whenever you need to:
  • Present a teacher led demonstration to a class of students
  • Introduce an experiment to the class
  • Share captured data from one group with the whole class
  • Provide training on how to use VISION

Please note. When using VISION connected to a display, we recommend the use of a Mouse (USB, Wired or Wireless)


With a PC

Connect VISION to a PC, and you can:

  • Use VISION as an interface, control VISION from the PC. Great for whole class demonstrations
  • Data captured on VISION can be transferred to the PC and opened directly into PC EasySense software.
  • Workroom setup files can be transferred to & from VISION.
  • Use Windows Explorer to manage VISION’s storage area - Delete, Copy, Rename etc

VISION to PC connection is simple and straight forward:
  • Connect VISION to the PC using the supplied USB cable.
  • VISION will appear as a removable storage device on the PC (No special drivers required).
  • Use Windows Explorer to drag and drop files between your PC and Vision


  • High resolution screen full colour, fast response to stylus or finger
  • EasySense software looks and behaves just like the PC version!
  • Fast datalogging for Physics (Up to 50,000 samples per second)
  • Long term remote datalogging (Up to 14 days logging on a single battery charge)
  • Battery life : A full ‘classroom day’ (User replaceable, rechargeable Lith-ION)

  • 4 SmartQ sensor inputs compatible with all SmartQ sensors
  • 2 SmartQ Digital inputs used as A & B for Time / Velocity & Acceleration experiments.

  • USB Client : Mouse, Wireless Mouse, Keyboard, Memory Stick, Powered USB Hub, Printers etc.
  • USB Host : Connect to a PC to run in interface mode and to transfer remote data
  • VGA Connection : Connect to a Projector or Monitor for whole class activities

The Vision data logger is marvellous, it is used several times a week, very popular.

Hassle-free data-logging with the EasySense VISION

It simplifies procedures that were the bane of my teaching life.

Data-logging breaks free of computers with VISION

Data-logging has suddenly got quicker. A lot quicker. Within two minutes of sitting down with Data Harvest's Barbara Higginbotham, we knew that the temperature was 22.3 degrees (the Royal Society for the Arts - RSA - likes to keep its premises comfortable), the humidity was surprisingly high at 58 per cent (well, it was pouring outside) and the sound level was an impressively low 50 decibels (a tribute to our whispers) but what do you expect in a library?

Data logger has multiple modes

Data Harvest is well known for easy-to-use and reliable dataloggers and EasySense VISION is no exception.

Institue Of Physics review by Chris Butlin

IOP - Logging with a self-contained unit

Alongside the logger, once paired with the Dynamics system (see separate review), you have a very powerful system for teaching a wide range of Physics.
