      from pysense import Pysense

      py = Pysense()

      volt_float = py.read_battery_voltage()

        @Camot Hello. I have both a Pysense and a Pytrack. I'm trying to read the battery voltage using "py.read_battery_voltage()", but I keep receiving the same values when the boards are connected to USB (with the batteries attached). For Pysense: 0.1203943 and for Pytrack 0.06017921. Thanks for your help.

          I am not sure I understand your point. Why do you expect a changing battery voltage when you board is USB powered? Unplug USB and you see the voltage decreasing slowly.

            @mqlopes When USB is connected the voltage is stable 3.3 Volts, while the battery is being charged. What you are asking about would require hooking into the battery itself, which is not the case.

                  Hi @papasmurph
                  What I understand is that it's the 3.3 volts who is tested with this function not the voltage of the battery ? Am I right ?

                    @Jiemde As far as I understand it's the driving voltage, so if connected to USB it's measuring the stable 3.3 Volt from the power supply, that then also charges the battery.

                        it should be:

                        from pysense import Pysense
                        

                        Note the capital P in the class name.

                          @daniel It has the same result in all the 4 combinations : pysense Pysense, pp, Pp and PP (it doesn't find the module pysense, if i delete it then it will not recognise the module LIS2HH12 and so on..). It is enough just to put the libraries in the same folder and then declare them in the code ?

                            How does your file system on the module look like? By default libraries are only searched inside the lib folder. Are you putting it there or somewhere else?

                            If you want to add other folder to the system path, you can do for example:

                            import sys
                            sys.path.append('/flash/my_folder')
                            

                            Cheers,
                            Daniel

                              @daniel you where right, I had all the libraries outside the lib folder and that's why it did not work.
                              still:
                              import sys
                              sys.path.append('/flash/my_folder')
                              helped me a lot! Thank you!
