Hi Deepak7434,

Thanks for contacting us.I think you shouldn't have problems with that, but I recommend you to power them externally because sometimes the Edison doesn't supply enough power for them.Additionally, check the UPM repository, you can find examples for the hx711 like this one: https://github.com/intel-iot-devkit/upm/blob/master/examples/c%2B%2B/hx711.cxxI hope you find this information helpful.Regards,-Leonardo

Thanks Leonardo

I am using an external supply to power my load cells.

I am using the library suggested by you.I want to know the unit of the return value of getUnits() function in the hx771 library .

Hi Deepak7434,

I'm not sure about it, but I recommend you to try to contact the author of the example. His email should be at the beginning of the example.Have a nice day.Regards,-Leonardo
