TTP223B Touch Sensor Module
The module is a capacitive touch switch module based on touch detection IC (ttp223b ). Under normal condition, the module outputs low level and the mode is low power consumption mode ; when touching the corresponding position with fingers , the module outputs high level and the mode switches to fast mode ; when there is no touch for 12 seconds, the mode switches to low power consumption mode . The module can be installed on the surface of non-metallic materials such as plastic and glass . In addition, 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 button hidden in the wall, desktop and other places . This module can help you avoid the trouble of pressing the button.
Inching type: the initial state is low level, touch is high level, do not touch is low level (similar to touch button function) low power consumption
The power supply can be 2-5.5V DC
Both sides can be used as the touch surface to replace the traditional touch button 4 M2 screw positioning holes for easy installation
Action notes: first touch the touch sensor lightly, and then press and hold the touch sensor for a long time, the desk lamp can flash and light for a long time
|Supply Voltage VCC
|Output High Level VOH
|Output Low Level VOL
|Output pin pouring current (@VCC=3V,VOL=0.6V)
|Pull current of output pin (@VCC=3V,VOH=2.4V)
|Response time (low power mode)
|Response time (fast mode)
Control Interface: three pins ( GND, VCC, SIG ) , GND is the ground, VCC is the power supply, SIG is the digital signal output pin
Power Indicator: green LED, light up when power on is correct
Touch Area: the internal area of an icon similar to a fingerprint, which can be triggered by the touch of a finger.
Positioning Hole: four M2 screw positioning holes, with an aperture of 2.2mm, make the module easy to install and position, and realize the combination between modules
