Without a Dimmer Switch, the light bulbs tend to glow at full brightness consuming maximum power. Touch the Touch ID sensor with your finger, but don't press it. The switches feature capacitive switch technology, also known as touch sensor. ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens). Design. Kungfu Mall AC 220V 3 Way Touch Control Sensor Switch Dimmer Lamp Desk Light Parts. US $4.00-$6.00 / Unit. 1 Unit (Min. You only need 3 components. A touch switch is a type of switch that only has to be touched by an object to operate. Static touch sensors detect hands and objects even through glass for as long as the sensing face is covered which provides, for example, protection against vandalism. Lower cost capacitive touch sensors are less advanced are and mostly used for human-device interfaces by measuring the capacitance change when a user's finger is nearby. Buy It Now. The touch sensors, the shield, and the guard sensor are all controlled by the PSoC. Mouser offers inventory, pricing, & datasheets for Capacitive Touch Sensors. 1/6. By swiping your finger perpendicular to the metallic sensor you can log on to the computer, a secure web page, or open a password protected program. Code. Like the previous project, the Proximity Detecting Light Switch, the touch sensor will be able to sense your hand from a few inches away. Allows you to remove the worry of conventional push-type keys. construction of sensors for touch-enabled products, and should provide an excellent starting point.
