[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 ...

An HVAC pressure sensor is particularly important in the cooling cycle—which includes compression, condensation, expansion, and evaporation—where it helps regulate refrigerant flow. Proper airflow ...

A dual resonator graphene sensor measures pressure with exceptional precision and stability, using built-in temperature compensation to maintain accuracy across wide pressure and temperature ranges.

[Bill Porter] is helping a friend out by designing a simple security system for her home. It relies on Xbee modules to alert a base station when doors are opened, or a pressure mat is stepped on. The ...
