Logger+Lite

=Logger Lite Software =

Getting Started:
1) Select a Vernier Sensor that you would like the use to gather data. For this example, we will use the Light Sensor.

2) Connect the sensor to the computer using a GoLink connector.

3) Open the Logger Lite Software (this can be done by double clicking the Logger Lite logo on the desktop, or by clicking the Start button, and searching for Logger Lite.

4) Once you have opened Logger Lite, you are ready to begin using the software. This is what the screen will display when you open the Logger Lite software.

Using the Tool:
<span style="font-family: Arial,Helvetica,sans-serif;">5) First, we will complete a trial run by collecting data to get an idea of how the software works.

<span style="font-family: Arial,Helvetica,sans-serif;">6) Holding the light sensor in one hand, click on the “Collect” button with your mouse. This will cause the sensor to begin collecting data, which will be recorded by the Logger Lite software.

<span style="font-family: Arial,Helvetica,sans-serif;">7.1) Logger Lite will record data in 10 second increments unless you enter a different amount of time (more about this on the second Logger Lite page). To end the collection of data at any time before the end of the 10 seconds, simply click the “Stop” button. The data that your sensor collects will appear on a graph as it is being recorded. The Logger Lite software will record the data by graphing the amount of illumination that is being collected by the light sensor per every .05 seconds. <span style="font-family: Arial,Helvetica,sans-serif;">The default graph that Logger Lite will create is a line graph.

<span style="font-family: Arial,Helvetica,sans-serif;">7.2) However, if you select “Options” from the top menu, then “Graph Options” you can change the style of the graph to a bar graph, which looks like this: <span style="font-family: Arial,Helvetica,sans-serif;">

<span style="font-family: Arial,Helvetica,sans-serif;">7.3) or a point protectors graph, which will look like this: <span style="font-family: Arial,Helvetica,sans-serif;">

<span style="font-family: Arial,Helvetica,sans-serif;">8) You will also use the “Options” “Graph Options” setting to add a title, which will appear at the top of your graph. <span style="font-family: Arial,Helvetica,sans-serif;">

<span style="font-family: Arial,Helvetica,sans-serif;">9) Now that we know the basic functions of the Logger Lite Software, we will begin experimenting with some of its other features. <span style="font-family: Arial,Helvetica,sans-serif;">First, we will try using the “Predict” feature. To begin, click on the “New” button to clear your old data. Now, click on the “Predict” button, then draw on the graph by clicking and holding down the left button on your mouse. After you select “Predict” a small pencil icon will appear on the graph where your mouse pointer used to be. This is to indicate that you are using a function that will allow you to draw on your graph. The “Predict” feature is used to show what kind of data you think the sensor will collect and how that data is going to appear on the graph. For instance, if you think that the sensor will begin by collecting a small amount of illumination then will have a sudden jump where it will receive a large amount of illumination, draw this on the graph. Once you have drawn your prediction, you can use the light sensor to collect data and compare the data that was collected by the sensor to the prediction you made. Click the “Collect” button to begin collecting data. <span style="font-family: Arial,Helvetica,sans-serif;">The data that the sensor has collected will appear on the same page as the graph that you drew. It will look something like this

<span style="font-family: Arial,Helvetica,sans-serif;">10) After you have created your prediction, you can experiment with the sensor and manipulate the amount of illumination that it is able to gather in order to try to match your prediction.

<span style="font-family: Arial,Helvetica,sans-serif;">11) In addition to recording the data that is collected by the sensor and by your prediction on a graph, Logger Lite also records the exact numerical value for the time and amount of illumination in a table so users can easily view the data. If you look to the left of the graph you will see a gray box. In this box, you will see the amount of illumination that is recorded per every .05 seconds. These numbers represent each point that is recorded on the graph. For instance, if we look at the recorded data in the gray box for the following graph at the 1.0 second mark, we will see that the amount of illumination that was recorded at that time was 177.3 lux. When we look at the graph, we will see that, at the 1 second mark on the x-axis, there is a dot at 177.3 on the y-axis. This feature offers users a quick, easy way to find the exact amount of illumination that was recorded during each .05 second increment. <span style="font-family: Arial,Helvetica,sans-serif;">

<span style="font-family: Arial,Helvetica,sans-serif;">12) Another way to determine the amount of illumination that was recorded at a certain moment in time is to use the “Examine” feature. <span style="font-family: Arial,Helvetica,sans-serif;">To use this function, click on the “Examine” button. This will create a line through your graph, which can be moved by moving your mouse. This function allows you to select any point on your graph to see the time and the amount of illumination that was recorded at this time. This function can be used to determine the moment in time and the amount of illumination for both the collected data and the predicted data. <span style="font-family: Arial,Helvetica,sans-serif;">
