Description
TTP223B Capacitive Touch Sensor Module Jog Type Digital Touch Pad Sensor Switch Electronic Capacitive Touch Switch
Product Description
This module is a capacitive touch switch module based on touch detection IC (TTP223B). Under normal conditions, the module outputs low level and the mode is low power consumption mode; when the corresponding position is touched with a finger, the module will output high level and the mode is switched to fast mode; when there is no touch for 12 seconds, the mode is switched to low again Power consumption mode. The module can be installed on the surface of non-metallic materials such as plastic and glass, and a thin piece of paper (non-metal) can be covered on the surface of the module. As long as the touch position is correct, it can be made into a hidden wall, desktop, etc. button. This module allows you to avoid the trouble of regular pressing buttons.
Feature
1, Inching type: the initial state is low level, touch is high level, and no touch is low level (similar to the function of tapping the button) 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, which can replace traditional touch buttons 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; Cooperate with optocoupler + delayer + bidirectional thyristor to complete the touch light of stairs.
