 Pololu FSR with 12.7 mm diameter circular active area are exhibits a decrease in resistance with an increase in the force applied to the active surface. Its force sensitivity is optimized for use in human touch control of electronic devices. The force vs. resistance characteristic provides an overview of FSR typical response behavior.  For interpretational convenience the force vs. resistance data is plotted on a log/log format. In general, FSR response approximately follows an inverse power-law characteristic (roughly 1/R).

 Measuring the Newton force by the FSR it is good idea to map analogue voltage reading ranges to 0 V to supply voltage. After that you can calculate the FSR resistance using following formula:
-R<sub>FSR</sub> = ((V<sub>cc</sub> - U) * R1) / U
+R<sub>FSR</sub> = ( (V<sub>cc</sub> - U) * R1) / U
