It enables touch-based control by detecting the presence of a finger on its integrated sensing pad, making it an excellent replacement for traditional mechanical push buttons in electronic projects and smart devices.\u003c\/p\u003e\n\u003cp\u003eThis module features a single touch-sensitive area measuring 11 x 10.5mm with an approximate sensing range of up to 5mm, allowing responsive and accurate touch detection. An onboard LED indicator provides instant visual feedback whenever the sensor is activated, helping users easily monitor the module’s operation.\u003c\/p\u003e\n\u003cp\u003eBy default, the sensor output remains LOW in an idle condition and switches HIGH when touched. The module also includes configurable solder jumpers that allow users to modify the operating behavior, including active LOW output mode or toggle mode functionality for versatile application requirements.\u003c\/p\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003eSpecification:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eModel: TTP223B \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOperating Voltage: \u003cspan\u003e2.5 ~ 5V DC\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003e\u003cspan\u003eOperation Mode: On-Off\u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003eFeatures:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSupports momentary or latching\/toggle modes.\u003c\/li\u003e\n\u003cli\u003eSupports Active High or Active Low output signal modes.\u003c\/li\u003e\n\u003cli\u003eThe response time max is ~60 ms in fast mode and ~220 ms in low power mode @VDD=3V.\u003c\/li\u003e\n\u003cli\u003eSensitivity can be adjusted by the capacitance (~0~50 pF).\u003c\/li\u003e\n\u003cli\u003eHave two kinds of sampling length by pad option (SLRFTB pin).\u003c\/li\u003e\n\u003cli\u003eStable touching detection of the human body for replacing the traditional direct switch key.\u003c\/li\u003e\n\u003cli\u003eProvides Fast mode and Low Power mode selection by pad option (LPMB pin).\u003c\/li\u003e\n\u003cli\u003eProvides direct mode and toggle mode by pad option (TOG pin).\u003c\/li\u003e\n\u003cli\u003eIn the open-drain mode by bonding option, the OPDO pin is an open-drain output, and the Q pin is the CMOS output.\u003c\/li\u003e\n\u003cli\u003eAll output modes can be selected as active high or active low by pad option (AHLBoutput, and the pin).\u003c\/li\u003e\n\u003cli\u003eHave the maximum on-time 100 sec by pad option(MOTB option (MOTBpin)\u003c\/li\u003e\n\u003cli\u003eHave an external power-on reset pin (RSToption (MOTB pin)\u003c\/li\u003e\n\u003cli\u003eAfter power-on it has about 0.5 sec stable time; during that time do not touch the keypad, and the function is disabled.\u003c\/li\u003e\n\u003cli\u003eAuto calibration.\u003c\/li\u003e\n\u003cli\u003eThe recalibration period is about 4.0 sec when the key has not been touched.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003ePin Description:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVCC: External 3.3V-5V\u003c\/li\u003e\n\u003cli\u003eGND: External GND\u003c\/li\u003e\n\u003cli\u003eDO: Digital output interface, could be connected to MCU IO port\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003ePackage Included:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cem\u003e1 x TTP223 Touch Switch Module\u003c\/em\u003e\u003c\/p\u003e","brand":"Generic","offers":[{"title":"Default Title","offer_id":43607631102119,"sku":"RS2607","price":10.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0618\/9042\/9095\/files\/NewProject_5e6785a4-d1dc-4645-a1d6-d386e39eb2c3.png?v=1779438290","url":"https:\/\/rees52.com\/products\/ttp223b-touch-button-sensor-module-capacitive-digital-switch-red","provider":"REES52","version":"1.0","type":"link"}
