Modern pressure sensor design and technology reduces potential damage from media, pressure transients, and condensation.

Some prebuilt sensor modules had some issues because of the 5V supply. In the end, he used a new sensor, a microcontroller, and then used the pump and valve from the blood pressure cuff.

[imsolidstate] built his own pressure sensitive mat. It utilizes two discs of copper clad board with a piece of foam in between for each of 64 sensors. As the foam gets compressed, the capacitance … ...
