For example, you could log the pH of a solution during a titration and analyze the graph later to find the equivalence point. Or, you could log the temperature of a server room to make sure the air conditioning system is working adequately, even when no one is there to verify.<\/pee>[\/et_pb_code][et_pb_code admin_label=”ph-button-cta: Start” _builder_version=”4.4.1″ box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″] <\/p>\n

What is a CSV and Why Use It?<\/h2>\n
CSV stands for Comma-separated Values. As the name suggests, you create a CSV file by simply writing data to a file as a string, and using commas to separate values. The benefit of using CSV files is that they are easy to generate (as shown in the code above) and you can open them with any spreadsheet program, like Microsoft Excel, to view and manipulate your data.For example, here is a CSV file opened using Excel:<\/pee>[\/et_pb_code][et_pb_image admin_label=”Excel Image” _builder_version=”4.6.6″ src=”https:\/\/www.phidgets.com\/education\/wp-content\/uploads\/2021\/01\/excel_csv.png” box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″ align=”center” width=”50%” show_in_lightbox=”on” \/][et_pb_code admin_label=”What is a CSV and Why Use It?” _builder_version=”4.6.6″ box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″]And here is the same file opened using Notepad:<\/pee>[\/et_pb_code][et_pb_image admin_label=”Notepad Image” _builder_version=”4.6.6″ src=”https:\/\/www.phidgets.com\/education\/wp-content\/uploads\/2021\/01\/notepad_csv.png” box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″ align=”center” width=”50%” show_in_lightbox=”on” \/][et_pb_code admin_label=”What is a CSV and Why Use It? contd” _builder_version=”4.6.6″ box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″]As you can see, the values are simply separated with commas. When writing these files from your code, you can move to a new line by adding the newline character \u201c\\n\u201d<\/strong> which is shown in the code above.<\/pee>[\/et_pb_code][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner _builder_version=”4.4.1″ box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″ module_id=”practice”][et_pb_column_inner type=”4_4″ saved_specialty_column_type=”3_4″ custom_padding__hover=”|||” custom_padding=”|||” saved_specialty_column_type=”3_4″][et_pb_code admin_label=”Practice” _builder_version=”4.6.6″ box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″]<\/p>\n
Practice<\/h2>\n
<\/p>\n
    <\/p>\n
  1. Try opening the generated file in a spreadsheet viewing program like Microsoft Excel or Google Sheets. Next, open the file in a text editing program like Notepad on windows or TextEdit on macOS.<\/li>\n
    <\/p>\n
  2. Modify your program to log the time in another column next to the temperature. Open the file in a spreadsheet viewing program and generate a graph that shows the temperature data vs time. Your file should look like this: <\/img><\/pee><\/li>\n
    <\/p>\n
  3. Create a CSV file that stores 1 data point from the temperature sensor and the humidity sensor every minute. Include a timestamp for each row. Run the program for 24 hours (or as long as you can). Do you notice any trends in the data (heating\/cooling cycles, lower\/higher humidity)? <\/li>\n
