Touch sensor module touch switch touch switch sensor 1 way

Touch sensorWhen touching by hand, S outputs a low level and the light is on. When touched again, S will output a high level and the light will be on. And so on!Power supply range: 3-5vCurrent: 5 maInterface: G (GND), V (VCC), S (signal)The module is a capacitive touch switch module based on touch detection IC (TTP223B). Normally, the module outputs low level and the mode is low power consumption. When you touch the corresponding position with your finger, the module will output a high level, and the mode will be switched to fast mode. When there is no touch for 12 seconds, the mode is switched to low power 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 position of touch is correct, it can be made into hidden buttons on the wall, desktop and other places. This module allows you to avoid the trouble of pressing a regular button.Module features are as follows:Touch mode: low in the initial state, high in touch, low in non-touch (similar to touch button function)Low power consumptionThe power supply can be 2~ 5.5v DCBoth the front and back can be used as touch surfaces to replace the traditional touch buttons4 M2 screw positioning holes for easy installation

Action note:

the light touch moving touch sensor, and then a little long time press and hold the touch sensor, you can achieve bright lamp and long light;

Control interface:

there are 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, light up when correct;Touch area: a fingerprint-like area inside the icon that can be triggered by the touch of a finger.

Positioning holes:

4 M2 screw positioning holes, the aperture of which is 2.2mm, make the module easy to install and position, and realize the combination between mod
