When using our GDX sensors with our programs, Graphical Analysis and Instrumental Analysis, or with a LabQuest, you do not need to know the channels of our GDX sensors, you just choose them from a list. If you are writing your own programs in Python, VPython, Web VPython, Arduino, JavaScript, knowing the numbers of the channels is important.<\/p>\n
Note that for the vast majority of sensors, programmers can just use channel 1. You can always check the channels by running this Python program gdx_getting_started_device_info.py. This program is available as part of our GDX Python collection at: https:\/\/vernierst.github.io\/godirect-examples\/python\/<\/a><\/a><\/p>\n You can also check the channel numbers by reading the sensor map in Graphical Analysis with the sensor connected. This is a complex file and it is a challenge to find the information this way.<\/p>\n Here is a list of GDX sensors (in alphabetical order by order code) and their channels.<\/p>\n
