Capacitive Sensor Interface Block Diagram A specialized analog front end converts the signal from the capacitive sensor into a digital value suitable for further processing (Fig. 7). It ...

The Raw Counts value is used to detect the presence of a finger on, or near, the sensor. Figure 3 shows the block diagram of a capacitive touch sensing pre-processing circuit. When you touch a button ...

The sensing field must change from the electromagnetic domain to the electrostatic domain; the inductive proximity sensor must become capacitive. Capacitive proximity sensors detect a wide variety ...
