Best arduino board for flex sensors

Projects General Guidance
1

Hi all,

I have a project where I need to be able to take readings from two flex sensors which will be back to back. The reason for this is that I'm told flex sensors only work well in one direction, and I want to be able to get the same measurements when the sensors are flexed the same angle in each direction.

First of all, which arduino board would you recommend so I can wire this up and then plug into my computer and get the readings? I need the smallest board capable of doing this.

Also, I would like to take readings/samples when the sensor is only flexed say up to 20 degrees to the vertical. Can the sensors be calibrated to show a decent reading on the screen at this angle??

Thanks guys!!

Any arduino should do as all you need are two A/D inputs.

Mind you flex sensor's are not that repeatable. Also you can not only read the sensor when it gets past a certain angle you have to read it all the time and only take note when it exceeds your threshold.

Hey Grumpy,
thanks for the response. What exactly do you mean by not that 'repeatable'?

I'm just getting into this stuff so not really up with the language just yet!

Perhaps I need a different type of sensor, a vibration or force sensor perhaps?

Cheers.

Not repeatable means that when the sensor is bent through exactly the same angle you do not get EXACTLY the same reading.

OK thanks for that info- that throws a spanner in the works.

@LeeVanGills,
I don't think you know him well enough to call him Grumpy. I would recommend "Mike".
