Measuring CO2 levels - Introduction

What is datalogging?

Data logging is a way of measuring variables in a laboratory or outside. It uses a computer, an interface, or data logger, and a sensor to monitor and record the results of scientific experiments.

Data logging is important because it:

  • gives immediate feedback of results;
  • gives easy analysis of results;
  • allows experiments to run for long periods of time;
  • gives you quick repetition of experiments;
  • helps you meet your science and ICT curriculum requirements;
  • helps you improve the accuracy of your experiments.

Classroom equipment

There are different manufacturers of data logging equipment. Most equipment from manufacturers works in the same way. Therefore, to carry out data logging experiments, you will usually need extra equipment and software, as well as a laptop. For this experiment, we have used sensors and software (EZscreen or DataStudio) from Pasco Systems that have sensors connected directly to the laptop.
As a teacher, you need not worry about going ahead with data logging with PasPort, even if you have no knowledge of the DataStudio program and the sensors. The idea is that pupils can work on their own after their teacher’s introduction. Data logging is to be regarded as an exciting addition to classroom learning.

Using the computer as a measuring instrument offers excellent opportunities for experimental studies. It is easy to set up the experiment and easy to read the test results. The pupils will soon work as small researchers and questions will arise: What if? Could we not? A scientist is in the making …

 

Description
Next to a computer, the USB link is the most economical way to use PASPORT when data is collected in the classroom. Just plug the sensor into the USB link, connect the USB link to the computer’s USB port and begin collecting data.

 

Computer Requirements

  • At least one USB port
  • EZscreen or DataStudio Software

 

Equipment Setup

  1. Install the EZscreen software included with all PASPORT sensors. EZscreen software only needs to be installed once.
  2. Connect a PASPORT sensor or sensor plug to the USB Link. Connect the USB Link to a USB port on your computer or USB hub. (Look for the USB icon shown to the right.)
  3. The software launches when it detects a PASPORT sensor. Select EZ-screen or DataStudio and begin collecting data.
