Touch sensor
When touched by hand, S output a low level, the lamp is bright; again touch, S will output high level, the lamp is bright; so repeatedly!
Power supply range: 35V
Current: 5MA
Interface: G (GND), V (VCC), S (signal)
The module is a capacitive point type touch switch module based on touch detection IC (TTP223B). Under normal conditions, the module outputs low level mode for low power mode; when the touch position corresponding with the fingers when the module will output high level mode switch for fast mode; when 12 seconds without touch, and switch to low power mode mode. You can install the module in the surface of nonmetal materials such as plastic, glass, in addition to the thin piece of paper (non-metallic) covered on the surface of a module, just touch the right position and can be made into a hidden in the walls, and other parts of the key desktop. This module allows you to avoid the worries of regular press keys.
Module features are as follows:
Point type: initial state to a low level, touch is high, do not touch to a low level (similar to the touch key function)
low power consumption
The power supply can be 2~5.5V DC
Both sides can be used as touch surfaces, instead of the traditional touch button
Action notes: first light touch moving touch sensor, and then hold down a touch point sensor for a long time, you can realize the desk lamp shining and long bright
