On further investigation we found another sensor called a ' Force Sensitive Resistor ' or FSR for short. The FSR did exactly what we needed by measuring direct force or pressure on the sensor.

This allows the distance between the bed and nozzle to be measured based on the force read by the resistor when placed in between the two. Using the tool is simple.
