Hello. I'm using arduino mega board and fsr 406(by interlink electronics, datasheet : https://www.devicemart.co.kr/goods/download?id=33868&rank=1) sensor. I used 1k ohm resistance and fsr 406 sensor and measured the voltage applied to the sensor. But even I just leaved the weight alone, the measured value had kept increasing. For example, when I put 200g weight on the sensor, the value immediately showed 160, but it increased to 190 in 20 seconds. I wonder why this happens.. The resistance of the sensor should be changed to explain it, but how can it happen?
Hi,
