Stable touching detection of human body for replacing traditional direct switch key.
Ttp223 capacitive touch switch module.
The ttp223 is a touch pad detector ic which offers one touch key designed for replacing traditional direct key button switch with diverse pad size.
Connect the components based on the figure shown in the wiring diagram using a m m pin connector.
A capacitive touch sensor module based on the dedicated ttp223 touch sensor ic.
At the heart of the circuit is an inexpensive 20 smd chip ttp223 commonly available in ba 6 package.
It s worth noting that the most common ttp223 module actually ttp223 ba6 module available as a stamp sized breakout board in red has onboard jumpers for active high low output mode selection and momentary toggle.
The module provides a single integrated touch sensing area of 11 x 10 5mm with a sensor range of 5mm.
The ttp223 ic at the heart of the module is a dedicated touch pad detector chip which offers a single capacitive touch key.
Vcc pin is connected to the 5v power supply gnd pin is connected to the gnd and the out pin is connected to the digital i o pin.
