interactive led touch screen razr p-80u.PSoC CapSense technology is implemented using CSA or CSD modules based on the principle of capacitive sensing. Parasitic capacitance will exist between adjacent sensing modules or wires on the PCB or touch screen (see Cp in Figure 4). When a finger approaches or touches two adjacent sensing modules, it is equivalent to adding two capacitors. It is equivalent to the capacitor Cf connected in parallel with Cp. The PSA's CSA and CSD technology can be used to detect changes in this capacitor, and determine if there is a finger touch.
