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.

[Marcus] has written up his experiences using the AD7746 capacitance sensor. He used the SparkFun breakout board in conjunction with an Arduino. The available Arduino code wasn’t that great so ...

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level ...

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 ...

NEWARK, DEL, Feb. 26, 2025 (GLOBE NEWSWIRE) -- The global capacitive sensor market is poised for significant expansion, with sales projected to rise at a steady compound annual growth rate (CAGR ...

This advancement in solution simplicity enables designers to include a capacitive sensing UI with less risk to the end-product development schedule. Essentially the UI design task has been reduced to ...

August 2, 2007 Alps Electric has completed development of the industry’s smallest (4.8mm long x 4.8mm wide x 1.8 mm high) capacitance type pressure sensor to detect absolute pressure.

In the last Sensor Sense we looked at capacitive touch switches used for ... That, in turn, lets a counter reach a higher count value to trigger the output of the touch circuit.
