Hello,

I have an Arduino UNO and I want to measure forces (up to 1600N) with a strain gaged block (which I already have). I have seen two SGS amps that you can buy, namely the HX711 load cell amplifier from Sparkfun and the Load Cell Amplifier Shield from Robotshop.

I want to measure the force from the SG and have each datum sample fed directly into an Excell spreadsheet so I can graph the output. Would I need an API to do achieve this or is there a nicer more elegant way to do this ?

And which load cell amplifier have you used and found to be the most useful / easy to use ?

(btw - the sample rate of the HX711 is 80 S/s)

Any ideas are appreciated.

Thanks

 

hi Andreas,
The HX711 has an input amplifier, with a Gain select option.
You can use the Arduino to serial output the weights to a PC, say in csv format which a Spreadsheet can import and plot.

EDIT:
This link has a lot of HX711 information.
