Touch sensor
When touched by hand, S outputs a low level and the light is on, when touched again, S will output a high level and the light is on, so repeat!
Power supply range: 3-5V
Current: 5MA
Interface: G (GND), V (vcc), S (signal)
The 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 wall, desktop, etc. button. This module allows you to avoid the trouble of regular pressing buttons.
The module features are as follows:
Inching type: the initial state is low level, touch is high level, non-touch is low level (similar to touch button function)
Low power consumption
The power supply can be 2~5.5V DC
Both front and back sides can be used as touch surfaces, which can replace traditional touch buttons
4 M2 screw positioning holes for easy installation
Action note: Lightly touch the moving touch sensor first, and then hold down the inching touch sensor for a long time, then the lamp can be flashing and long on,
Control interface: a total of 3 pins (GND, VCC, SIG), GND is the ground, VCC is the power supply, and SIG is the digital signal output pin,
Power indicator: green LED, it lights up when power on correctly,
Touch area: the inner area of ??the icon similar to a fingerprint, which can be triggered by a light touch of a finger.
Positioning holes: 4 M2 screw positioning holes with a diameter of 2.2mm, which make the module easy to install and position and realize the combination between modules,
