Diycart TTP223 Touch Key Switch Module Touching Button Capacitive Switches Self-Locking/No-Locking Jog For Arduino Electronic Components Electronic Hobby Kit

Ttp223 capacitive touch sensor module. The ttp223 is a touch pad detector ic replicating a single tactile button. This touch detection ic is designed for replacing traditional direct button key with diverse pad size. Features: supports momentary or latching/toggle modes. Supports active high or active low output signal modes. Dimensions: 15mm x 11mm. Input voltage: 2v-5. 5V dc. The response time max ~ 60ms in fast mode, ~220ms at low power mode at vdd=3v. Sensitivity can adjust by the capacitance(0~50pf). Have two kinds of sampling length by pad option(slrftb pin). Stable touching detection of human body for replacing traditional direct switch key. Provides fast mode and low power mode selection by pad option(lpmb pin). Provides direct mode toggle mode by pad option(tog pin). Open drain mode by bonding option, opdo pin is open drain output, q pin is cmos output. ). After power-on have about 0. 5Sec stable-time, during the time do not touch the key pad and the function is disabled. Auto calibration. Re-calibration period is about 4. 0Sec, when key has not be touched.
