Hey there, so we’ve ordered a few pressure sensors ( RP-L-400 Thin Film Pressure Sensor) to be used for a model we are creating,
I was wondering if there was a comprehensive datasheet that outlines the resistance (R) to force (g) ratio graph provided on the website (I attempted to search but only came to wiki.dfrobot, which came up with limited information) - I was also wondering if there was a comprehensive explanation of the sensors themselves, while testing I observed different resistance readings when placing a weight along the sensor at different points? (since pressure is force over area, I was wondering if the sensor had other mechanisms to calculate its force)
I was also wondering if cutting the sensors in to shorter strip and soldering them would reduced the performance of the sensors? (if so I believe obtaining the 170mm version of the sensor would be better)
Furthermore most of the tests have been measured using a multimeter, understandably an arduino set up would be a better option for real time data recording, have there been any tutorials similiar, on setting up a simple resistance measuring device with this pressure sensor?
Sorry for the lengthy questions, and thank you everyone for reading.
