Conductive targets affect capacitive sensors as well, but in a different way. When a conductive target enters the sensor field it forms a counter electrode to the active face of the sensor.

A capacitance proximity sensor most often used for industrial automation is mounted in the wooden base. He just calls it “an NPN capacitive sensor” without mentioning part number but these are ...

Capacitive sensing offers developers a new way to interact with users that overcome the traditional problems associated with mechanical levels or push button switches that engage a solenoid controlled ...

Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, posi… ...

With capacitance sensors, one can observe different growth and death phases in real time. Capacitance is a direct measurement: You know exactly what is being measured, namely charge buildup around ...

Capacitive reactance (Xc) increases as capacitance decreases and continues to grow to the point where virtually all the voltage drop occurs across this now open element of the circuit. Any remaining ...

The type of capacitive sensor utilized in smartphone screens is capable of assessing a user's current hydration level, via a press of a finger ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front ...

The capacitive sensing controller monitors the sensor capacitance by converting the measured capacitance into a digital value. Mechanical buttons replacement with capacitive sensing buttons ...

Meanwhile, a capacitance sensor measures the electrical charge in the leaf. Water conducts electricity differently than the leaf material, and the sensor can read that.

Capacitive touch switches combine to simulate an analog control. In the last Sensor Sense we looked at capacitive touch switches used for on/off control. But these switches are also found in ...
