You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...

Here is a simple capacitive touch switch circuit for electronics hobbyists. Even though the circuit uses smd components, construction of the touch sensor switch is not very hard because the whole ...

Here's a nice one for those looking to incorporate LEDs with a touch or proximity switch into a project: the company Bare Conductive shows how to use an LED strip light with its Touch Board. The ...

This PLL-based circuit implements a touch-switch circuit using the PC board or small metal pads as sensors; it is radiometric and thus insensitive to changes in temperature and supply voltage.

Capacitive touch sensors have made homes i n scores of MP3 players and mobile phones. Of course, the mobile arena is no longer the only bastion for these devices. Today, sensor technology has ...
