ICT : Data Logging

Explain what does the term ‘Data Logging’ means

The automatic or manual capture and storage of data for use at some time in the future

If you are planning to carry out a data logging experiment, what sorts of decisions will you need to think about before you begin?

1) what type of data am I collecting

2) what form do I wan to pressent it in

3) how will i collect it (i.e. what sensors will I use)

4) what type of data collection method shall I use (i.e. manual, automatic or remote)

Explain in your own words the differences between:

• manual data logging
• automated data logging
• remote data logging

manual data logging:

automated data logging:

remote data logging:

Give two situations where automatic data logging equipment could be used to record data over a long period of time

Identify the reasons why it might be better to use automatic data logging rather than manual data logging.

Are there any disadvantages when doing this?

Give four examples of different types of sensors and state where they might be used.

Explain why an analogue-to-digital converter is needed to transform the data collected by the sensors.

A water company uses a sensor to detect the acidity of the water in its reservoirs. Describe what happens to the data from the sensors.
