Interfacing 2 load cells with arduino uno for measurement of lift and drag forces

Community General Discussions

Hi everyone,
I’m currently carrying out a wind tunnel project using an Arduino-based DAQ system for acquisition of lift and drag data. I would love love to log the data directly into MS EXCEL using PLX DAQ. However, I can’t seem to figure out how to correctly wire and interface lift and drag load cells to the arduino.

Will using the Robotshop 2-channel load cell shield solve my problem?

Thanks in advance for any advice and help.

Regards

Hi,

The RobotShop Load Cell Shield should work fine with any wheatstone bridge based devices as load cells. Actually, this shield is a perfect fit for your application since it has two channels load cell inputs for your lift and drag load cells. You can take a look at this blog post to have a better idea on how you setup the shield with an Arduino board and a load cell. You can download the Arduino library through this link.

Hope this helps,
