Data Logging 01
This KS3 ICT quiz will ask questions on data logging. Data logging is a means of collecting and storing data. The data stored on a datalogger is temporary and will be lost the next time it is used. For that reason, the data is downloaded to a computer as a file so that it can be permanently stored and processed. Processing of data from a data logger is often done using a spreadsheet as that is software that can easily produce a graph or other chart from a table of numbers. Graphs and charts can help people make sense of a series of numbers more easily.
Data loggers obtain their data from sensors. There are a large range of different ones that can record many changes in the environment - temperature, humidity, light level and so forth. Sensors are designed to convert the information about the environment into electrical signals which can be stored as data. They work automatically, that is to say, once they have been programmed by a person, they can be left in the environment for long periods of time without the need for anyone to be there.
