I’ve hooked up a FSR following the tutorial from bildr Force Sensitive Resistor + Arduino - bildr but I have an issue where the value slowly climbs by a couple of points every couple of minutes when the force is static. The sensor is under a rubber mat which has a coffee pot resting on top. At first I thought it was possibly related to temperature but the value never stabilized and continued to climb. If I take the load off, and then put it back on it will “reset” but then start climbing again. Is this just the nature of the sensor or is there possibly something else going on? Another thing to note is I swapped out the resistor for a 1K instead of a 10K so it takes more force to register readings.
