PSLab is a small USB powered hardware extension for your Android phone or PC that
lets you measure all kinds of things. PSLab comes with a built-in
Oscilloscope, Multimeter, Wave Generator, Logic Analyzer, Power Source,
and we are constantly adding more digital instruments. PSLab is many
devices in one. Simply connect two wires to the relevant pins and start
measuring. You can use our Open Source Android or desktop apps to view
and collect the data. You can also plug in hundreds of compatible I²C
standard sensors to the PSLab pin slots. It works without the need for
programming. What experiments you do is just limited to your
imagination!
