Description
TTP223-BA6 Digital Touch Switch Latch Type Capacitive Touch Light Switch Hand Touch Panel Switch Board
Product Description
This module is a capacitive latch type touch switch module based on the touch detection IC (TTP223-BA6), and the touch IC is in the trigger mode (Toggle Mode). The module can be installed on the surface of non-metallic materials such as plastic and glass, and the touch sensing area can be made into buttons and switches hidden on walls, desktops and other places. Eliminate the trouble of conventional pressing mechanical buttons and switches.
Feature
1, Latch type: the initial state can be set to high or low level, touch will change the level state (similar to self-locking switch function) 2, Low power consumption 3, The power supply can be 2~5.5V 4, Both front and back sides can be used as touch surfaces, DC can replace traditional self-locking switches 5, 4 M2 screw positioning holes for easy installation
Application
With optocoupler + bidirectional thyristor, smart home projects such as touch fluorescent lamps can be completed; With optocoupler + delayer + bidirectional thyristor, it can complete the touch light of stairs.
Tapping the latch type touch sensor twice in succession can realize the light on and off; among them, the 5V single-circuit relay module is connected to the light.

Installation Instructions
Pin description
Control interface: a total of 3 pins (GND, VCC, SIG), GND is the ground, VCC is the power supply, SIG is the digital signal output pin, and it outputs high level when it is powered on; Power indicator: green LED Touch area: The inner area of the icon similar to a fingerprint, which can be triggered by a light touch of a finger.
