When you touch the sensor, the module's output state will also switch from the idle low level to the high level\u003c\/li\u003e\r\n         \u003cli\u003eNon-contact Trigger: You can install the capacitive touch sensor on the surface of non-metallic materials such as plastic and glass, and cover the surface of the module with a thin piece of paper (non-metal). As long as the touch position is correct, it can be made into a button hidden in the wall, desktop, etc\u003c\/li\u003e\r\n         \u003cli\u003eWiring Method: Touch switch only needs to connect 3 pins, VCC connects to 2~5.5V power supply (3.3V or 5V is recommended); GND is grounded; SIG is the output signal, connected to the GPIO of the MCU\/development board (such as Arduino D2, Raspberry Pi GPIO18)\u003c\/li\u003e\r\n         \u003cli\u003ePositioning Hole: 4 x M2 screw positioning holes with a hole diameter of 2.2mm, making the module easy to install and position, and realizing the combination between modules\u003c\/li\u003e\r\n         \u003cli\u003eWide Application: TTP223B capacitive touch sensor is widely used and can be applied to smart homes, such as hidden wall switches, touch table lamps; electronic DIY, such as replacing mechanical buttons; can also be used for waterproof\/dustproof panels; can also be used for consumer electronics, etc\u003c\/li\u003e\r\n  \u003c\/ul\u003e","brand":"YELUFT","offers":[{"title":"Default Title","offer_id":44154547699892,"sku":"B0FHK5CBV1","price":96.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B0FHK5CBV1.jpg?v=1775787034","url":"https:\/\/auspowers.com\/products\/20pcs-ttp223b-digital-capacitive-touch-sensor-module-touch-switch-dc-2-5-5v-for-arduino-raspberry-pi","provider":"AusPower Australia","version":"1.0","type":"link"}
