Hi
I have one of the Short Flex Sensor Product ID: 1070 . I've connected it up to some wires via solder and placed it between some thin neoprene. This seems to work OK but I've noticed that while at rest it seems to be a bit noisy i,e, bouncing around +/- 3. Is this normal or could it be that the circuit is on breadboard? It's connected to an Arduino Nano IOT 33. I'm using the circuit here (https://learn.adafruit.com/force-sensit ... ing-an-fsr) without the LED and a 5K resistor instead.

Re: Short Flex Sensor
Sounds like the +/- 3 is the raw ADC reading? If you're running the example sketch from that page, that's the value that gets printed after "Analog reading = ". If so, then seeing a variation of 3 counts is generally expected. That's just general "noise" in the data signal.

Re: Short Flex Sensor
Ah, I see. Is there a way to make it more accurate (via an external ADC converter chip)? Or is there a way of stabilising it?

Re: Short Flex Sensor
Easiest approach is to take multiple readings and average them in software.
