This circuit can be used to detect finger pressure or any force on a surface with the help of a pressure sensitive sheet material called 'velotstat'. You can find a tutorial how to build the physical sensor [https://learn.bela.io/tutorials/pure-data/sensors/diy-pressure-sensor/ here]. | This circuit can be used to detect finger pressure or any force on a surface with the help of a pressure sensitive sheet material called 'velotstat'.

The same circuit can be used with a different type of physical interfaces as well. Instead of the velostat material as a variable resistor we can use a layout of wires known as a 'moisture sensor'. | The same circuit can be used with a different type of physical interfaces as well.

We can hookup our moisture sensor to the circuit above instead of the velostat sandwiched between two electrodes.
